Fixed Mutant loot module

Moved to bpatch system for much better compatinility across other mods.

Rebalanced all mutants to be more dangerous but fair, while slightly nerfing some abilities. Some high lights:
Fleshes will run away more often and be much noisier.
Pseudodogs now have much less annoying clones (Wont bleed, cause screen shake or break armor) but the real dog does much more damage.
Pseudogiants now shake your screen and deal more damage but are slower.
All mutants have a bit more armor penetration to provide a challenge with high tier armor

update for game version 1.6

Made Burer more balanced
Small changes to all Mutants
Chimera now uses its new behaviour system

Made burers easier to fight by increasing their shield cooldown and reducing their armor

Added missing effects
