Major changes: do not delete and recreate markers and curves for every tempo map change, attach tempo curves directly to their (preceding) tempo marker, notable cleanup of TempoCurve class to remove unnecessary members. More tweaks expected since algorithm for matching markers and tempo map points is not correct yet.
