Compressed nibble arrays.

https://github.com/SpigotMC/Spigot/blob/master/CraftBukkit-Patches/0012-Compressed-Nibble-Arrays.patch

Entity ticking chunk caching.

https://github.com/SpigotMC/Spigot/blob/master/CraftBukkit-Patches/0044-Entity-ticking-chunk-caching.patch
- Cache known loaded chunks so we avoid making a potentially expensive contains call for every single entity in exchange for some simple arithmetic.
- Best case scenario, this cuts down contains call to once per chunk, worst case it adds on some simple arithmetic operations
