    Notify user about question dialogs
    
    Set an urgency hint on dialog's parent, or dialog itself, when it has
    no parent, to get user's attention to the dialog. For example, when
    there is a changed mail composer window on a different workspace than
    evolution's main window and user invokes quit by File->Quit in evolution,
    then the window is waiting for a response on the composer, but there
    was no hint it's waiting for anything.
