David Robillard ee1477f9b6 Fixed random track background problem 
Cleaned up StreamView initialization (cause of above problem)
Fixed other StreamView colour issues (incomplete port from GTK1 by the looks of it)
Added new narrower playback (top) toolbar (under 1024 now?  maybe?)
Cleaned up status-in-menubar stuff (to be a bit narrower/nicer)
