Bug 17170: Add admin page for filters and ability to edit/save existing filters

This patchset adds a new ability to save searches on the staff client, and display them in the results
page on staff or opac as a new filter.

New filters can be added from the resuilts page after a search, and there is an admin page for updating
deleting and renaming filters

There is a new permission to control management of these filters

New filters can be added that are not displayed along with facets, this allows for building custom links
using these filters to keep URLs shorter
