Overflow menu for the now playing screen. New home for the info screen here. Adds quick navigation to current album or artist (thanks tjk!) and clear queue button.

Also fixed up the way the now playing screen looks when queue is cleared (remove previous duration and don't show "loading" if nothing is actively loading).

This fixes the case where you switch from a file with an artist to one
with no artist, which would show the old artist.

The album field is already hidden, title shows the filename if missing,
and the track info screen is fully reset, so this covers everything
currently present.

Queue now has a separate 'ready' property to indicate it's ready to be used, which is independent from whether it's still loading tracks in. This also improves the response time for shuffling all tracks (we will initially pick a random track in the first 100 tracks whilst the rest of the tracks are loading). This should also fix issues where one song will start playing and then repeat itself when the queue finishes loading, and hopefully solve #160 as well (though I couldn't actually repro this myself).
