Official country names used by the ISO 3166/MA
Main changes are:
For "countries_id" in table we use "ISO 3166-1 numeric" value.
We are need to change because sometimes new country/region have new code (we need add new countries for countries_table, what method country_id are correct?) & most contributions prepare zones for shipping method. In contributions use countries_id value. This vaule "ISO 3166-1 numeric" are prepare by ONZ & I belive: will be constans for most of year.
