Locale data - important for multi-language countries

See countries/country_select#206

A use case I have is that I want to use Faker to generate locale-specific data. It looks like this isn't the most standardized thing in the world, but hopefully possible? I store the country, so it'd be nice to do something like:

Faker::Config.locale = address.country.locales.first

Not the most elegant thing in the world, but I think this is a reasonable use case: given a country what are the possible locales.
