(From update of attachment 197466)
This doesn't build since I added the removetrack event, and I need some time to figure out how to handle some things better.

The most annoying part of this is that Vector<RefPtr<TrackBase> > can't be cast to Vector<RefPtr<TextTrack> >, which makes TextTrackList.cpp significantly more complicated than it needs to be. I'm thinking I can just make m_elementTracks and m_addTrackTracks(?) into Vector<RefPtr<TrackBase> > also, but it will make the code more complicated. I think if I move the track index and isRendered() code into TrackBase it will work, I just need to make sure that those make sense for audio and video tracks.
