	Connection diagram - How the initilization works.
	
	Client -> INFO -> Server
		Contains version info, name, and some other info.
		
	Client <- MAP <- Server
		Contains current map.
	
	Client -> READY -> Server
		The client has loaded the map and is ready to go,
		but the mod needs to send it's information aswell.
		modc_connected is called on the client and
		mods_connected is called on the server.
		The client should call client_entergame when the
		mod has done it's initilization.
		
	Client -> ENTERGAME -> Server
		Tells the server to start sending snapshots.
		client_entergame and server_client_enter is called.
