Add English as a language
Add columns:
identifier: same as iso639 except 'roomaji' for Roomaji
order: English first, then Japanese and Roomaji, others undefined
official: True for all the languages so far
Language codes are ISO 639-1; country codes are ISO 3166-1 alpha-2.
The country codes are important to keep for flags and stuff, I guess,
but reporting the language code as a short form for the language is
more correct.
Gonna see if I can do that, I guess. I added the language codes mostly
just because I was adding languages.
