improved the water code so that immunity wont trigger if the entity has the water pathfinder system active, so this improves support for all entities that know how to behave in water. Merged 2 EAR patches together, and removed an MCUtil method that doesnt have a purpose anymore

Subject: [PATCH] Optimize getChunkIfLoaded type calls
|
|
|
|
Uses optimized check to avoid major locks and large method.
|
|
|
|
Will improve inlining across many hot methods.
|
|
|
|
Improve getBrightness to not do double chunk map lookups.
