JSF Learning Path Updates and Additions

Hey Rich,

In this pull request, I've removed the Liferay Faces Bridge, Alloy, and Portal sections and turned them into tutorials. I also did some minor rearranging to the module containing those sections to make it stylistically pleasing.

I also created the new learning path on creating a JSF Control Panel portlet, which accomplishes the same tasks as the MVC Guestbook Control Panel portlet.
