Add an option to use the same interpreter Spyder is running on as "Python executable" for external consoles

Spyder Version: 2.2.2 (2977: r4aca4472a8d0 )
Python Version: 2.7.5
Qt Version: 4.8.4, PyQt4 (API v2) 4.9.6 on Windows

Creating a new IPython console fails and returns the following traceback in Console plugin:

NOTE: When using the ipython kernel entry point, Ctrl-C will not work.

To exit, you will have to explicitly quit this process, by either sending
"quit" from a client, or using Ctrl-\ in UNIX-like environments.

To read more about this, see ipython/ipython#2049 To connect another client to this kernel, use:
--existing kernel-5816.json

That's because you are using IPython 1.0 (the message about using Ctrl+\ to kill the kernel reveals it) and we support only 0.13.x.

But don't despair, I have almost ready a commit to make 2.2 work with 0.13 and 1.0.

Summary: IPython 1.0 is broken in Spyder v2.2.2 (was: IPython may be broken in Spyder v2.2.2)

No, actually I'm using IPython v0.13.2, that's why I was worried by this bug:

Python 2.7.5 (default, May 15 2013, 22:44:16) [MSC v.1500 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

IPython 0.13.2 -- An enhanced Interactive Python.

Wait... false alarm!

This was a terrible mess in settings in my WinPython installations... I copied Spyder settings from a WinPython folder to another and so the Python executable option (Console>Advanced) was still pointing the Python interpreter of the old WinPython install. Maybe we should warn the user when the Python interpreter executing Spyder has changed and is different from the one specified to run programs inside Spyder. For me it's not really a problem, I realized in about 2 minutes where the problem was. But for other people, this can be more tedious. A colleague once told me about a similar problem: he changed from a Python distribution to another (so same Spyder settings, but different interpreter for Spyder execution), and he had problems with Spyder... after a long while, someone else made him realized that the Python interpreter used by Spyder to run programs was not the right one.

Status: Invalid

Implemented in revision 47bc3bf36d4e the necessary change I was referring to in my previous comment.
