Vantage Mobile Menu: Allow GTranslate to add flags to the mobile menu

[Misplon]

The following aren't able to add content to the mobile menu:

GTranslate flags
https://wordpress.org/plugins/shortcode-in-menus/
https://wordpress.org/plugins/widgets-in-menu/

It would be helpful for users to keep their menu flags in the mobile menu once added to Appearance > Menus.
