Misc Changes:
	- Score is now modified by the difficulty setting. The higher you go, the more score you get!
	- The alpha skies can now be switched on and off for mapsets that supply new ones.
	- Hell lightning was reimplemented in ZScript, now only lighting up sectors exposed to the sky.
	- The Anti-BD/Anti-HDoom script was disabled due to it maliciously crashing the engine, and also due to my views on that kind of thing changing. However, they seem to crash with the mod anyway due to a few missing null checks. Whoops!
	- Tom is King
