JellySquid d454bbd5e1
Implement JellySquid's Entity Collision optimisations patch 
This patch replaces the vanilla collision code for both block and entity collisions with faster implementations by JellySquid, used originally in her Lithium mod.

Optimizes Full Block voxel collisions, and removes streams from Entity collisions
