        * app/gui.[ch]: make gui_libs_init() use gtk_init_check() and return
        a gboolean on success or failure.

        * app/main.c: reorganized so that --help and --version never need
        the gui to be initialized. Print a proper message when the gui cannot
        be initialized (perhaps recommend --no-interface?). Return nonzero
        exit status on failures.
