Pathogen : Monster plague

-NEW PATHOGEN CONTAMINATION SYSTEM

-New pathogen fluid (doesn't spawn naturally at the moment)

-Added 15 "incomplete forms" (ex : mutated sheep, cow, guardian, golem...), results of the contact between a vanilla creature and pathogen. Incomplete forms will transform into one of the different mutant species( for ex : walker, prowler...) after 10 minutes, regarding the creature infected and the biome where it was contaminated. Infected life forms will attack every other creatures, transforming them into mutant forms of themselves upon death.

-Added 2 subspecies of the swimmer : reef and river

-Added 2 entirely new mutant species : the Marauder (basically an armor shredder) and the Infector which well... infect other life forms  and transform then into an incomplete form

-Added a brand new armor, it costs ALOT of ressources but is worth it. 

-nerfed ender creatures spawn

-reworked swimmers animations and texture

-reworked the scale armor items texture

-changed crafts 

-reworked the catalyst model

-added a new "potion effect" : Pathogen infection. When this effect expires, the entity will transform into an intermediate form which will later transform in one of tthe mutant main species

-reworked the [BIOME] Strenght effect icons

-Various bugs and glitches were removed

The next update will focus on models/ texture reworks, a deepening of the contamination system, and some new elements...
