- Fixed: Dehacked string replacement did not check the clusters' finaleflats.

- Changed the definition of several typedef'd structs so that they are
  properly named.
- Limited DEHSUPP lump lookup to search zdoom.pk3 only. It will no longer
  be possible to load DEHSUPP lumps from user WADs.
- Brought back the text-based DEHSUPP parser and changed it to be able to 
  reference states by label. Also changed label names of 
  DoomUnusedStates and added proper labels to all states that were
  previously forced to be the first state of an actor so that the old
  (limited) method could access them. This was done to address the following
  bug:
- Fixed: The player's death states calling A_PlayerSkinCheck should not be
  part of the state set that is accessible by Dehacked. These will produce
  error messages when mapped to non-players.
