Fixed facet list on collections page.  Facet list now simply adding new facets rather than setting an action parameter.  Encoding search query when it is forwarded from the basic search form controller to the search results controller.  Using search query parameters minus search state (row, sort, etc) for facets, search forms and breadcrumbs, so that you can't end up on page 20 with 1 page in the results after faceting.
Sorting in public interface working, no longer going through BasicSearchFormController.  Title sort in public using lowercase field and sorting the right direction.  Sort parameter now parsed into type and order by search state parser
