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] 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.
