Subject: [PATCH] Ensure Entity AABB's are never invalid
If anything used setPositionRaw, it left potential for an AABB
to be left stale at their old location, which could cause massive
AABB boxes if movement ever then got called on the new position.
This guarantees any time we set the entities position, we also
update their AABB.
