[GSoC Update] Playdar Integration, Week 6

[Andy Coder]

Hey folks,

Lots of work on PlaydarCollection/PlaydarQueryMaker, (and supporting
the collection in other components), this week.  I got set back a bit
on PlaydarQueryMaker, (was hoping to build things this weekend), but
I've got it sorted out on paper now, and some uncommitted code.
Things should be running shortly, (I think I covered the collection's
behavior last week).
