DDF-847 - Added Enhanced Search to the search ui.

-added less to build.  Most of the css I added is in less.
-added the enhanced search query build inside the arrow dropdown on the
search results page.
-added ApplicationHelpers to hold global overrides for different
libraries.  Can be used later.
-anyGeo needs to be address (in other tickets).
I'd like to not have this class in here.
