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] Provide E/TE/Chunk count stat methods
Provides counts without the ineffeciency of using .getEntities().size()
which creates copy of the collections.
