Subject: [PATCH] Significantly improve performance of the end generation
This patch implements a noise cache for the end which significantly reduces the computation time of generation. This results in about a 3x improvement.

Subject: [PATCH] MC-4: Fix item position desync
This fixes item position desync (MC-4) by running the item coordinates
through the encode/decode methods of the packet that causes the precision
loss, which forces the server to lose the same precision as the client
keeping them in sync.
