* Added compatibility for Hellbound MAP29
- Some of the ceilings in the monster closets weren't high enough to allow the cyberdemons to pass, making 100% kills impossible. This is caused by the floors not going down far enough and stopping at a certain height above the next closest floor.
* Remove the cyberdemons instead of raising the ceilings.
Removed the red key door compat patch for Illusions of Home E3M7 because a switch (the computer panel, rather) already opened that door as it was, therefore the original change was unnecessary.
* Fix issues in ILLUSORY/ilusory1
Added some compatibility patches for Illusions of Home E1M6, E3M4, and E3M7 (this fixes minor issues to all of these maps)
E1M8 requires a MAPINFO of some sort to have work correctly in the state it's in, unfortunately.
* Minor tweak to ILLUSORY/ilusory1 fix
Didn't need the activation reset as it was already set to begin with.
* Made the fixes consistent
Made the fixes consistent with the rest of the fixes for the other WADs already in this file
- e5m2: floating skulls disappear on lower skill levels
- e5m4: the platform with the baron of hell that led to the invulnerability secret had a missing texture
