Search Updates

This is not finished but a great place to merge for testing by Kavinga to start.

I delete the legacy search screens and routes and code.
This search is the default.
Add the ability for Search Refinement through filters. This feature only supports common filters as per DSC-166. Still need to implement the common filters.

The code will need some minor refactoring and I still need to workout SOLR joins and how they relate to the user interface.

Also added the route for @snezanam exporting story she is currently working on.
