    app: Add File -> Debug -> Dump Keyboard Shortcuts menu command
    
    Add a Debug menu item 'Dump Keyboard Shortcuts' that can for example
    be used to see what keyboard shortcuts that are unused or to simply
    get an overview of what current keyboard shortcuts we hvae. Based on
    code in gimp_action_view_new().
