Merge branch 'audiomsg_overhaul' (nonshared eventlists and more)

This introduces the following changes:
 - Clone Parts no more share their eventlist. Instead, all changes
   made to one clone are replicated to the other clones' eventlists
 - audio/song->msg{Add,Delete,Change}{Part,Event,Track} have been
   replaced by the corresponding UndoOp operations.
 - Enforcing of const-correctness: No GUI code may ever gain
   writable access to audio/midi/song data structures. Access
   must *always* go through applyOperationGroup. This is now
   enforced.
 - Removed a bunch of DELETETHIS or REMOVE or otherwise commented
   out code
 - Removed dead code
 - Removed unused Audio Messages (that should go through applyOpGroup
   anyway.)
