1042extcmd packet. Ext commands will be processed in the order they are
1043received by the server, like other user commands. The first argument is
1044the logged-in player. Ext commands can only be processed after a player
1045has logged in successfully.

1051
1052Register a callback for execution when the client sends an (asynchronous)
1053exticmd packet. Exti commands are processed by the server as soon as they
1054are received, i.e. out of order w.r.t. other commands. The first argument
1055is a client socket. Exti commands can be received anytime, even before
1056log-in.
