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).
This was a weird one.  So metadata-content-type was coming back as a XML string instead of a plain text value.  <contentType value="theValue"/> vs "theValue".  I used $ to parse the xml.  I do need to remove this workaround code.
