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] Extend Player Interact cancellation
GUIs are opened on the client, meaning that the server cannot block them from opening,
However, it is possible to close these GUIs from the server.
Flower pots are also not updated on the client when interaction is cancelled, this patch
also resolves this.
