 If a plugin / theme author has to add input fields to the navigation menu
 editor, the only way is to extend the `Walker_Nav_Menu_Edit` class,
 replicate the `start_el` function, and modify this function to add fields.
 This can cause issues upon core upgrades. I am attaching a patch that
 includes an action hook after all the core fields are shown, so that
 plugin / theme authors can use this hook to add more custom fields. A
 corresponding hook for saving is not needed, since
 `wp_update_nav_menu_item` takes care of that.
