    MessageDialog: Correct the get_message_area() return type.
    
    * gtk/src/messagedialog.hg: get_message_area(): Return a Box instead of a VBox.
    This may have worked already, but this is a minor API change that should not
    affect anybody too much, and hopefully it will be OK this soon after the 3.0.0
    release.
