Can't load config.ini

[rambit]

Config doesn't seem to load or save on Linux.

A quick fix was to remove pathSeparator from configEditor.cpp but probably not a cross platform solution.

Also globalFunctions.cpp cannot mkdir because it has a ~. It worked when replaced with /home/user

I also tried to do this to check if it exists:

if (0 != mkdir(appconfigdir.c_str(),0733)) {
  perror("mkdir");
}
