Current Chunk for Entity and Block Entities, counts by entity type
This enables us a fast reference to the entities current chunk instead
of having to look it up by hashmap lookups.

We also store counts by type to further enable other performance optimizations in later patches.

Subject: [PATCH] Add system property to disable book size limits
If anyone comes in with a watchdog crash related to books after this patch
you will not only be publicly shamed but also made an example of.
Disables the security limits on books entirely, allowing plugins AND players
to make books with as much data as they want. Do not use this without
limiting incoming data from packets in some other way.
