    app: Show "(overwritten)" and "(exported)" status of image
    
    When an import source has been overwritten with File -> Overwrite
    <file.png>, or exported by whatever means, reflect this status in the
    title bar of the image window. Do this by adding some string building
    logic to gimp_display_shell_format_filename().
