Moved struct definition to separate file, and added check for displaying GUI

Browse Source 
I moved the GameType struct (and the Mode enum) to a separate file, as I will need
to use it in the check_server and check_client functions as well. I also added the
signum function (which was previously in sign.hpp) to this file, since it was the only
function in sign.hpp. Finally, I added a check, that will only display the GUI, if the
user didn't provide any command-line arguments.
