Moved the elasticsearch provider to
platform/persistence/elastic. Then moved
the search aggregator and the generic
provider into a services folder within
the search folder.
Slight tweak to the padding of the search view,
which affects where the top of the scroll bar
appears. Also removed the search scroll div
because it was unused.
The controller's loadMore function now sends
new queries to the search service if the
controller's full results list does not have
enough results in it to load more.
