Merge XSL with jQuery Mobile

[scottgonzalez]

We should just have a single XSL for jQuery UI and jQuery Mobile. Right now we have separate files with slight differences. Ideally we would merge with the jQuery Core XSL as well.

e598e77 moves the example template into a new stylesheet. This will allow us to share entries2html-base.xsl across all projects and still have customize example templates. If we find other places that need to be customized per project, we can follow the same pattern.

As of jquery/api.jquerymobile.com@a47614a jQuery Mobile is in-sync with jQuery UI. There's one exception, which is that jQuery Mobile has a theming section. I didn't pull this back into jQuery UI because I'm not sure if it should exist (see jquery/api.jquerymobile.com#2).

The theming section has been removed.
