Added packet_level_respawn_info to inform the players of entity
deletions in a different area of the same level. Currently it's
massively noisy due to sending out a new packet for each entity
destroyed. This can cause chaos when collecting a series of coins.
Ideally this information would be batched and sent in one big blob every
so often.
Removed (slightly) old coin and static ent removal system
Resynchronized respawners
Added packet for macro deletions
better than previous system since the entities don't need a sync id and we can synchronize deletion station across areas
allows the synchronization of odd entities like lines of coins
Added packet for spawn info deletions
Split packet_location_request into multiple files
