Subject: [PATCH] Optimize sending packets to nearby locations (sounds/effects)
Instead of using the entire world or player list, use the distance
maps to only iterate players who are even seeing the chunk the packet
is originating from.
This will drastically cut down on packet sending cost for worlds with
lots of players in them.
