Beta 4: Dr. Demented's Den

[RobSeegel]

Here's the latest batch of changes, which should include area 4. I may be adding another BBB or two, still. These changes were somewhat lighter than in area 3, except for the entrance to two yellow doors which was moved, because I deleted three rooms that guarded them.  I saw no reasonable way to make these rooms easier in a short time, with more in the mansion that needed to be addressed.

If you are cautious about playing any x-hard sections, then I would stop once you've gotten to room 16309 where there is a save point. That's the next section I'll be double-checking.
