- 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. SVN r1512 (trunk)
