PictureFlow: Switch between albums from track view

Prev/next buttons on iPods or Fiio M3k can now
be used to select another album without having to
return to the albums view first. Scroll wheel/strip
handles scrolling up and down in the track list
as before.

Other targets probably have the necessary
buttons for this, so the keymap can be extended
in the future (same goes for alphabetic browsing)

Also prevents queue overflow and handles
failure case for track list tagcache retrieval.
