        * button-widget.c:
        (button_widget_theme_changed): reload the icon when the
        icon theme changes.
        (load_pixbuf), split out from button_load_pixbuf().
        (button_load_pixbuf): try loading with the icon basename
        first and if that fails use the full path. This will ensure
        that launchers with absolute paths for icons will theme
        correctly, #106649.
        (button_widget_instance_init): connect to the icon theme's
        'changed' signal.

        * launcher.[ch]: (free_launcher), (setup_button): remove handling
        the icon theme's "changed" signal here.
