[wmii] liblitz fontset implementation

Hello,

i would opt for adding something like that in blitz_loadfontset:

        if(missing) {
                while(nmissing--) {
                        fprintf(stderr, "liblitz: missing fontset: %s\n", missing[nmissing]);
                }
                XFreeStringList(missing);
        }

Greetings,
Denis
