    Work around Qt failing to use correct role and/or state
    
    Checkable menu items should have STATE_CHECKABLE and/or the role of
    ROLE_CHECK_MENU_ITEM. Apparently this is not always the case for Qt
    apps. This workaround should cause Orca to announce the checked state
    when present, but not announce "not checked." In order for the latter
    to occur, Qt apps should fix the aforementioned bug.
