Filter on non-person/collection facets

HYDRASIR-272
Uses explicit query hash for add_facet_field on
non-person/non-collection facets. This query should probably be creted
by enumerating through all of the types of works.
Also, does not filter out persons and collections if you hit the "More
Types of Works>>" link when there are more than five facets available.
