Customization Header/Footer/Homepage - Optional new landing page for installation

[mheppler]

Based on feedback from the community (#2003), we will provide configurable settings to allow for an installation to enable a custom landing page as the homepage, as well as custom header and footer for their Dataverse application.

This issue, along with the custom configuration features outlined in #3637 and #3638 will provide a flexible solution for installations to brand their Dataverse application as they may choose with content, images, messaging, etc.

To add a record to the settings table so that the app can find a custom file outside the war file(Also have to update SettingsServiceBean):
INSERT INTO setting(
name, content)
VALUES (':HomePageCustomizationFile', '/Applications/Custom/testCustom.xhtml');

• Adding this from Navbar Customization - Nav links for About and Guides #3637:

• Logo: display a logo in the navbar in place of orange Dataverse logo

  • This will be another external file
  • A setting will specify whether or not to look for the logo externally

x-Search in the navbar from custom homepage throws error.
x-Browse Data button on sample custom homepage not working. (Mention to use your own root dv alias)
x-Search in navbar from real homepage returns user to custom homepage with no results.
x-Show how to remove options
x-Add a bit more guidance on logo config/sizing.

I just spoke with @sekmiller about the todo list above and will be making a few small documentation tweaks.

@sekmiller I implemented the documentation improvements we talked about in c05ae5e and you and @dlmurphy and others are welcome to take a look. I also merged the latest from develop into the pull request (#3639).
