Double-check localization code usage. ISO 639-1

[gregjurman]

Double check if server is using the four letter language code(en-US, es-ES) or just the two(en, es). Much like The Queen's English (en-GB) verses 'murican (en-US), there are differences between the Spanish (es-ES, es-MX) languages as well.

Most systems will spit out a four letter code for i18n/L10n compliance as it is a user preference. The server should respect the four letter code, and only degrade to two if there is no direct match.

I think we'll just split on "-" and take the first part. That is how it is currently implemented. Will keep this open for discussion though.
