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.
