Subject: First shot at support for the Hexen 4-level Demo

With these changes it is possible to run the game using the HEXEN.WAD
IWAD from the 4-level Demo and start a new game as one of the three
player classes.

Known missing bits:
 - The game does not yet identify itself as the demo version
 - The cheat codes are still unchanged
 - Bug compatibility, see e.g.
