Clean up a lot of obfuscation helpers and impls
This fixes a bug with obfuscation helpers for attack cooldown
But every other change should stay the same.

Cleaning up a lot of helpers that pointed to already unobfuscated items.
Also adds final to many of the obfhelpers to assist with inlining.

This is pretty much a patch maintenance

Subject: [PATCH] Ignore Dead Entities in entityList iteration
A spigot change delays removal of entities from the entity list.
This causes a change in behavior from Vanilla where getEntities type
methods will return dead entities that they shouldn't otherwise be doing.
This will ensure that dead entities are skipped from iteration since
they shouldn't of been in the list in the first place.
