speeded up structural operations

fixed several heavy bugs in structural operations:
 - global insert freezed muse
 - global cut and global insert behaved wrong on parts not
   starting at the zeroth tick
 - fixed upper_bound vs. lower_bound issues
clicking below the track list now deselects all tracks
moved checkRegionNotNull() where it belongs
