CHG: filterbox: Completely updated to AJAX changes, and reworked function.

* It now uses the 'dosearchmodifykeywords' hook to change the query instead
  of messing with the $search directly.
* Therefore it now supports filtering searches like !collection as well, as
  it should have from the start.
* Moved it below the global search box instead of appearing above it.

ADD: filterbox: optional instant filter update.

* Applies the current filter live during text input (after a short delay, that is).
