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] Auto Save Improvements
Makes Auto Save Rate setting configurable per-world. If the auto save rate is left -1, the global bukkit.yml value will be used.
Process auto save every tick instead of once per auto tick interval, so that chunk saves will distribute over many ticks instead of all at once.
Re-introduce a cap per tick for auto save (Spigot disabled the vanilla cap) and make it configurable.
Adds incremental player auto saving too
