Spottedleaf da9d110d5b Remove chunk save reattempt patch
This patch does not appear to be doing anything useful, and may
hide errors.

Currently, the save logic does not run through this path either
so it did not do anything.

Additionally, properly implement support for handling
RegionFileSizeException in Moonrise.

Subject: [PATCH] Don't run entity collision code if not needed
Will not run if:
Max entity cramming is disabled and the max collisions per entity is less than or equal to 0.
Entity#isPushable() returns false, meaning all entities will not be able to collide with this
entity anyways.
The entity's current team collision rule causes them to NEVER collide.
