        * launcher.[ch]: add a destroy_handler to the
        launcher structure. Helps in the destroying the
        properties dialog when launchers are dragged and
        dropped.
        * panel.c (drop_internal_icon) disconnect the
        destroy handler on the properties dialog and
        explicitly destroy it. Fixes #97112.
