+		The client has loaded the map and is ready to go,

+		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.
