Merge branch 'monster-misc-2' into 'master'

Monster misc 2

Just some clean-up in doomdef.h, nothing important or majorly game-breaking really. It's all stuff that apparently hasn't been used by the game itself in many years by now.

...

inb4 I find something else obsolete to kill later and make monster misc branch no. 3
