+	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.
