CQL QueryBox in the Examine page.

I've ripped out the filter boxes for individual columns in favor of the monolithic search box. Typing "ORDER BY sample:GQ" will update the sort arrows in the appropriate column. The inverse (clicking the arrow) doesn't update the query (yet!).

This also renames a few things to be more uniform.
