Similar to policy set viz interface by Joshua.

I implemented getMatchingNodeFacets(query = filters + text). The facets are currently sources only.

Standard faceted search =
query for "all facets" before filters (query = text only or the whole database if no text was specified)
query for "current facets" after filters (query = filters + text)
For searchbox full text search all facets = current facets to start out with.

Then display checkboxes for "selected" current facets out of all facets.
All facets stays the same throughout the faceted search process, since text is not changing. If the user enters a new search and text changes, then the facets are also reset.

Added facets as a side panel to the search results page. We could still add a detail page, not sure.
