[gh-240] [#989] Digital Signage II (The Flexible Way)

Previous work on display boards was very limited in scope to one design.

This is a ticket to commit against for work on a module that will handle parsing any XML (and eventually JSON) and setting generic display settings (rotate content vs show it all).

Also the original design will be refactored into a new theme that is less UNL specific.
