MediaPlayer: support multiple tracks in one file
for example vorbis chained streams (one file, multiple tracks) right now a vorbis file with multiple tracks is shown as one (very long) track.
the same is true for cue-sheets, pls, m3u for large mp3's and so on.
i like to have as little clutter as possible and it's also less space consuming as using single files for each track. (as just one block might be "not-full" instead of n for n files for n tracks).
update: no change up to sailfish 2.0.2.43
