    GtkMenuButton: use :toggled instead of :clicked
    
    :toggled is triggered on :clicked, so using :toggled lead to the menu
    to be popped up at the same time, while allowing to use the toggle state
    and avoiding any need to a hack to prevent recursion, which somehow
    wasn't enough for double emission of GtkMenuToolButton:show-popup.
