Aikar 2d7e5dce25
Disable Vanilla last chunk access cache, use ours
Also fixes some bugs in ours

Ultimately they both are near the same, but ours is behind the synchronized gate.

Mojangs is mixed behind 2 different synchronization contexts (chunks can lock 2 different objects)

Mojang also blindly unsets the ref on any chunk unload, not just if its the one being pointed to.

Subject: [PATCH] Prevent Auto Save if Save Queue is full
If the save queue already has 50 (configurable) of chunks pending,
then avoid processing auto save (which would add more)
