queue/playlist display screwed up if tabs span over multiple rows in the tab bar

[6arms1leg]

when opening more playlists than can be displayed in one tab row, the track lists are somewhat misplaced and overlap the tab bar.

Ah yeah, I can see that problem, but actually the UI needs a lot of cleanup in the background before this can be resolved cleanly. The problem is, that most components are too tightly coupled already, and fixing this quickly (just hacking in some mesurements, to make sure the playlist is pushed down a bit), would only result in more code debt and even slower developement in the future. So please be patient while I clean up things in the background...
