Fixes for German language.

Fix a bug with equipping using the quick keys: when item is already equipped, equipping it again would cause the slot to get unequipped first, possibly restacking and destroying the Ptr that was supposed to be equipped in the first place
Make sure the equipped weapon HUD icon is updated properly
Don't update actors while paused
Initialize mFallHeight
Change setKeepParticlesInLocalSpace to false. Not correct for all particles, but the opposite isn't either. Plus it breaks pretty much all magic VFX.
Lots of cleanup. Implemented Absorb and Resist. Implemented several instant effects. Added hand VFX.
