Please add "Niue" to the list of countries

Thank you very much, Vladimir. By the way, please also list «MAYOTTE» in the Indian Ocean, which has the same political status as «REUNION», «FRENCH GUYANA», «MARTINIQUE» and «GUADELOUPE». Also, please list «MONSERRAT» in the Caribbean, which has the same political status as «CAYMAN ISLANDS» and «ANGUILLA». Спасибо тебе, дорогой друг. There is a flag for New Caledonia. Don't forget to supply it.
