Spottedleaf 38dc3b25d8 Optimise chunk tick iteration
When per-player mob spawning is enabled we do not need to randomly
shuffle the chunk list. Additionally, we can use the NearbyPlayers
class to quickly retrieve nearby players instead of possible
searching all players on the server.

Subject: [PATCH] PlayerNaturallySpawnCreaturesEvent
This event can be used for when you want to exclude a certain player
from triggering monster spawns on a server.
Also a highly more effecient way to blanket block spawns in a world
