Various Mixin-related Fixes

[glowredman]

This PR includes:

• General cleanup
  • Update deps
  • Remove dead code
  • Add missing @Override annotations
  • Fix generics
  • Add serialVersionUIDs
  • Address deprecation warnings
  • Use @WrapWithCondition v2 instead of the deprecated v1
  • Replace static method access using objects with static method access using types
• Use AccessTransformers instead of mixins (I know some don't like them but they make the code more readable, don't add new instructions and don't create conflicts with other mixins doing the same thing)
• Fix two conflicts with ArchaicFix
• Add @Mutable annotations to @Final fields that are modified
• Fix two injection targets (one incorrectly specified remap = false, the other can be solved without having to shift by 2)
