Track timing, smaller menus, fewer bugs.
Added 'missing album' artwork.
Work around silly text rendering bug.
Update state after skipping to beginning of track.
But actually scroll marquee text when necessary.
Marquees now use animations instead of explicit timers.
Random tweaks/stabs in the dark.
Don't spuriously reset the track scrolling.
Use sequence numbers to avoid duplicate messages.
Removed defunct code from main menu.
