Hi,

I was wondering if we could extend the CountryType via an option to make it support ISO_3166-1 Alpha-3 country codes as listed here:

http://en.wikipedia.org/wiki/ISO_3166-1_alpha-3

I'm currently working on a project where I need country codes as 3 characters instead of just 2.

Would it be possible to include a new alpha3 option or something to support 3 characters country codes?

Edit: I saw that @umpirsky already compiled a list of all countries data in several formats: http://dev.umpirsky.com/list-of-all-countries-in-all-languages-and-all-data-formats. I don't see any ISO 3166 support in these files...

@fabpot @bschussek any thoughts?
