Add Basic "How To Run A Full Node" Page

Add basic page with some general information plus instructions for
Ubuntu 14.10.

Change a link on the participate page to point to the full node page.

This page is being added as English-only for now.  I figure we can
convert it into a translation template after we have instructions for
Windows and Mac OS X, and after the instrutions have actually been
tested with the released version of Bitcoin Core 0.10.0.  (These Ubuntu
instructions were tested with RC3 and the old Ubuntu packaging.)

+## What Is A Full Node?
+
+A full node is a program that fully validates transactions and blocks.
+Almost all full nodes also help the network by accepting transactions
+and blocks from other full nodes, validating those transactions and
+blocks, and then relaying them to further full nodes.
+
+Most full nodes also serve lightweight clients by allowing them to
+transmit their transactions to the network and by notifying them when a
+transaction affects their wallet. If not enough nodes perform this
+function, clients won't be able to connect through the peer-to-peer
+network---they'll have to use centralized services instead.
+
+Many people and organizations volunteer to run full nodes using spare
+computing and bandwidth resources---but more volunteers are needed to
+allow Bitcoin to continue to grow.  This document describes how you can
+help and what helping will cost you.
+
+## Costs And Warnings
+
+Running a Bitcoin full node comes with certain costs and can expose you
+to certain risks. This section will explain those costs and risks so you
+can decide whether you're able to help the network.
+
+### Special Cases
+
+Miners, businesses, and privacy-conscious users rely on particular
+behavior from the full nodes they use, so they will often run their own
+full nodes and take special safety precautions. This document does not
+cover those precautions---it only describes running a full node to help
+support the Bitcoin network in general.
+
+Please [consult an expert](/en/community) if you need help setting up
+your full node correctly to handle high-value and privacy-sensitive
+tasks.
+
+### Secure Your Wallet
+
+It's possible and safe to run a full node to support the network and use
+its wallet to store your bitcoins, but you must take the same
+precautions you would when using any Bitcoin wallet.  Please see the
+[securing your wallet page](/en/secure-your-wallet) for more
+information.
+
+### Minimum Requirements
+
+Bitcoin Core full nodes have certain requirements. If you try running a
+node on weak hardware, it may work---but you'll likely spend more time
+dealing with issues. If you can meet the following requirements, you'll
+have an easy-to-use node.
+
+* Desktop or laptop hardware running recent versions of Windows, Mac OS
+  X, or Linux.
+
+* 50 gigabytes of free disk space
+
+* 2 gigabytes of memory (RAM)
+
+* Broadband Internet connection
+
+* 6 hours a day that your full node can be left running. (You can do
+  other things with your computer while running a full node)
+
+### Possible Problems
+
+* **Legal:** Bitcoin use is [prohibited or restricted in some
+  areas](http://bitlegal.io/)
+
+* **Anti-virus:** Several people have placed parts of known computer
+  viruses in the Bitcoin block chain. This block chain data can't infect
+  your computer, but some anti-virus programs quarantine the data any
+  way, making it more difficult to run a full node. This problem mostly
+  affects computers running Windows
+
+* **Attack target:** People who want to disrupt the Bitcoin network may
+  attack full nodes in ways that will affect other things you do with
+  your computer, such as an attack that limits your available download
+  bandwidth or an attack that prevents you from using your full node's
+  wallet for sending transactions
+
+## Linux Instructions
+
+The following instructions describe installing Bitcoin Core on Linux
+systems.
+
+### Ubuntu 14.10 Desktop
+
+*Instructions for Bitcoin Core 0.10.0.*
+
+Click the Ubuntu swirl icon to start the Dash and type "term" into the
+input box. Choose any one of the terminals listed:
+
+![Dash term](/img/full-node/en-dash-term.png)
+
+Type the following line to add the Bitcoin Personal Package Archive
+(PPA) to your system:
+
+    sudo apt-add-repository ppa:bitcoin/bitcoin
+
+You will be prompted for your user password.  Provide it to continue.
+Afterwards, the following text will be displayed:
+
+     Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
+     More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
+    Press [ENTER] to continue or ctrl-c to cancel adding it
+
+Press enter to continue. The following text (with some variations) will
+be displayed and you will be returned to the command line prompt:
+
+    gpg: keyring `/tmp/tmpixuqu73x/secring.gpg' created
+    gpg: keyring `/tmp/tmpixuqu73x/pubring.gpg' created
+    gpg: requesting key 8842CE5E from hkp server keyserver.ubuntu.com
+    gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created
+    gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported
+    gpg: no ultimately trusted keys found
+    gpg: Total number processed: 1
+    gpg:               imported: 1  (RSA: 1)
+    OK
+
+Type the following line to get the most recent list of packages:
+
+    sudo apt-get update
+
+A large number of lines will be displayed as different update files are
+downloaded.  This step may take several minutes on a slow Internet
+connection.
+
+<div class="box" markdown="1">
+*Choose one of the following options*
+
+1. To install the Bitcoin Core Graphical User Interface (GUI), type the
+   following line and proceed to the [Bitcoin Core GUI](#ubuntu-gui)
+   section below:
+
+        sudo apt-get install bitcoin-qt
+
+2. To install the Bitcoin Core daemon (bitcoind), which is useful for
+   programmers and advanced users, type the following line and proceed
+   to the [Bitcoin Core Daemon](#ubuntu-daemon) section below:
+
+        sudo apt-get install bitcoind
+
+3. To install both the GUI and the daemon, type the following line and
+   read both the [GUI instructions](#ubuntu-gui) and the [daemon
+   instructions](#ubuntu-daemon). Note that you can't run both the GUI
+   and the daemon at the same time using the same configuration
+   directory.
+
+        sudo apt-get install bitcoin-qt bitcoind
+
+After choosing what packages to install, you will be asked whether you
+want to proceed.  Press enter to continue.
+</div>
+
+#### Bicoin Core GUI {#ubuntu-gui}
+
+To start Bitcoin Core GUI, click the Ubuntu swirl icon to open the Dash,
+type `bitcoin`, and click the Bitcoin icon.
+
+![Dash Bitcoin-Qt](/img/full-node/en-dash-bitcoin-qt.png)
+
+You will be prompted to choose a directory to store the Bitcoin block
+chain and your wallet.  Unless you have a separate partition or drive
+you want to use, click Ok to use the default.
+
+![Bitcoin-Qt Welcome](/img/full-node/en-bitcoin-qt-welcome.png)
+
+Bitcoin Core GUI will begin to download the block chain.  This
+step will take at least several hours, and it may take a day or more on
+a slow Internet connection or with a slow computer.  During the
+download, Bitcoin Core will use a significant part of your connection
+bandwidth.  You can stop Bitcoin Core at any time by closing it; it will
+resume from the point where it stopped the next time you start it.
+
+![Bitcoin-Qt Initial Block Download](/img/full-node/en-bitcoin-qt-ibd.png)
+
+After download is complete, you may use Bitcoin Core as your wallet or
+you can just let it run to help support the Bitcoin network.
+
+<div class="box" markdown="1">
+*Optional: Start Your Node At Login*
+
+Starting your node automatically each time you login to your computer
+makes it easy for you to contribute to the network. The easiest way
+to do this is to add Bitcoin Core GUI to the list of startup
+applications.
+
+Click the Ubuntu swirl icon to start the Dash, type `startup app`,
+and click the Startup Applications icon.
+
+![Dash Startup App](/img/full-node/en-dash-startup-app.png)
+
+In the screen that appears, click the Add button, and enter the
+following information.  The `-min` tells Bitcoin Core GUI to start
+minimized (in the tray):
+
+       Name: Bitcoin
+    Command: bitcoin-qt -min
+
+The form should look like this:
+
+![Startup Applications Bitcoin-Qt](/img/full-node/en-startup-applications-bitcoin-qt-min.png)
+
+Click Save and then Close to save your changes. The next time you login
+to your desktop, Bitcoin Core GUI will be automatically started in as an
+icon in the tray.
+
+![Bitcoin-Qt Tray Icon](/img/full-node/en-bitcoin-qt-tray-icon.png)
+</div>

+
+#### Bicoin Core Daemon {#ubuntu-daemon}
+
+Before using the Bitcoin Core daemon, `bitcoind`, you need to create its
+configuration file with a user name and password. First create the
+`.bitcoin` directory, create (touch) the file, and set the file's
+permissions so that only your user account can read it.  From the
+terminal, type:
+
+    mkdir .bitcoin
+    touch .bitcoin/bitcoin.conf
+    chmod 600 .bitcoin/bitcoin.conf
+
+Then you can run the command `bitcoind`.  It will print output similar
+to this:
+
+    bitcoind
+    Error: To use the "-server" option, you must set a rpcpassword in the configuration file:
+    /home/bitcoinorg/.bitcoin/bitcoin.conf
+    It is recommended you use the following random password:
+    rpcuser=bitcoinrpc
+    rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+    (you do not need to remember this password)
+    The username and password MUST NOT be the same.
+    If the file does not exist, create it with owner-readable-only file permissions.
+    It is also recommended to set alertnotify so you are notified of problems;
+    for example: alertnotify=echo %s | mail -s "Bitcoin Alert" admin@foo.com
+
+The "rpcpassword" displayed will be unique for your system.  You can
+copy the the rpcuser and rpcpassword lines into your configuration file
+using the following commands.  Note that in most Ubuntu terminals, you need
+to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C
+and Ctrl-V have different meanings in a Unix-style terminal.
+
+    echo rpcuser=bitcoinrpc >> .bitcoin/bitcoin.conf
+    echo rpcpassword=XXXXXX >> .bitcoin/bitcoin.conf
+
+(**Warning:** Don't use XXXXXX as your RPC password. Copy the
+rpcpassword displayed by bitcoind for your system.)
+
+Now you can start Bitcoin Core daemon for real.  Type the following
+command:
+
+    bitcoind -daemon
+
+It will print a message that Bitcoin Core is starting.  To interact with
+Bitcoin Core daemon, you will use the command `bitcoin-cli` (Bitcoin
+command line interface).  Note: it may take up to several minutes for
+Bitcoin Core to start, during which it will display the following
+message whenever you use `bitcoin-cli`:
+
+    error: {"code":-28,"message":"Verifying blocks..."}
+
+After it starts, you may find the following commands useful for basic
+interaction with your node:
+[`getblockchaininfo`](/en/developer-reference#getblockchaininfo),
+[`getnetworkinfo`](/en/developer-reference#getnetworkinfo),
+[`getnettotals`](/en/developer-reference#getnettotals),
+[`getwalletinfo`](/en/developer-reference#getwalletinfo),
+[`stop`](/en/developer-reference#stop), and [`help`](/en/developer-reference#help).
+For example, to safely stop your node, run the following command:
+
+    bitcoin-cli stop
+
+A complete list of commands is available in the [Bitcoin.org developer
+reference](/en/developer-reference#rpc-quick-reference).
+
+When Bitcoin Core daemon first starts, it will begin to download the
+block chain. This step will take at least several hours, and it may
+take a day or more on a slow Internet connection or with a slow
+computer. During the download, Bitcoin Core will use a significant part
+of your connection bandwidth. You can stop Bitcoin Core at any time using
+the `stop` command; it will resume from the point where it stopped the next
+time you start it.
+
+<div class="box" markdown="1">
+*Optional: Start Your Node At Boot*
+
+Starting your node automatically each time your computer boots makes it
+easy for you to contribute to the network.  The easiest way to do this
+is to start Bitcoin Core daemon from your crontab.  To edit your
+crontab, run the following command:
+
+    crontab -e
+
+Scroll to the bottom of the file displayed and add the following line:
+
+    @reboot bitcoind -daemon
+
+Save the file and exit; the updated crontab file will be installed for
+you. Now Bitcoin Core daemon will be automatically started each time
+your reboot your computer.
+
+If you're an Ubuntu expert and want to use an init script instead, see
+[this Upstart
+script](https://github.com/bitcoin/bitcoin/blob/2d782ab2ce30bf106e34cd3288c9082ac04022f9/contrib/init/bitcoind.conf).
