    application: let GtkApplication automatically load the app-menu
    
    GtkApplication automatically loads menus from the GtkBuilder resource
    located at "gtk/menus.ui", relative to the application's resource
    base path (see g_application_set_resource_base_path ()). The menu
    with the ID "app-menu" is taken as the application's app menu.
