kind of work.

Outstanding issues:
*) They aren't saved and restored properly
*) The "more" and "fewer" buttons in the dialog don't do anything
*) The stuff for marking a playlist "dirty" isn't really working so the
   search might not be updated when the data in the collection list
   changes

But this all will follow shortly.
