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] Fix FileIOThread concurrency issues
|
|
|
|
FileIOThread was using two volatile counters in order to track if
|
|
any pending work was in the queue, this causes potential concurrency
|
|
issues when this counter is updated from multiple threads, potentially
|
|
causing these counters to desync due to the unsafe volatile update
