* New Lua bindings SONGMAN:GetGroupNames() and SONGMAN:GetSongsInGroup(string)
* Add Lifts to PaneDisplay (StepMania 3.9+ added them)
* Fix an issue where course banners were able to trip off the uneven dimensions dialog
* NextSong/PrevSong now work when TwoPartSelection=true + TwoPartConfirmsOnly=true on ScreenSelectMusic. A new message ("TwoPartConfirmCanceled") was added to catch when this happens.
and there may have been some stray cleanup in here too
