    util: Add an option to request dialogs being modal
    
    As WMs cannot open windows themselves, Mutter uses zenity to open
    "Force Quit" dialogs for unresponsive windows; as those are strongly
    tied to the corresponding window, it makes sense to make them modal
    (in particular when attaching them to their parent).
