creates empty directoriy when started with option -game <nonexisting dir>

[j4reporting]

starting ironwail from cli with the -game <mod> option will create an empty directory if mod name doesn't exist.

Maybe print an error message and don't start or fail back to ID1 and don't create any empty directory in gamedir
