specialsource-maven-plugin also renames echopet methods if methods collide

[Arnuh]

Example is EntityAgeablePet#setBaby(boolean) which overrides a method in Mob resulting in it getting renamed to obf name and baby petdata toggling failing

Only solutions I can think of are to rename such methods or request/add a way to filter methods to https://github.com/md-5/SpecialSource/

As mentioned in d169736, with #106 slowly making pets the 'real' entity we will be moving away from "IEntityXXPet" and instead handling any setting of variables for a pet via "EntityXXPetBase". This will allow the PetBase class to properly get its method calls remapped to the obfuscated naming without renaming our setters.
