QVGA: smaller font size for lists

Currently on QVGA devices, you can only see about 3 entries in any list. Maybe 4 if this suggestion would be implemented: http://ampdroid.userecho.com/dash/topic/43058-move-volumepauseprevnext-to-now-playing/

I think it would be a good idea to make the font size for the list entries much smaller on QVGA devices (+ decrease the minimum height of an entry), to make more items visible at the same time.
