Server sends all clients (except for host) serialized entity data when a replicated entity is spawned
Deserialize entity creation message data on client, attempt to create and spawn
Bail instead of throwing exception on recv var for entity that doesn't exist yet (need to stop vars coming in before entity creation)
Enable new entity replication again, previous commit fixed the fuckup
Send destroy entity message
Destroy replicated entity on client when receiving destroy entity message
Add test entity that despawns after 5 sec to test entity destroy message
