Setup i18n

[mohebifar]

That would be a good idea if you implement the localisation settings.

I'm definitely going to do this at some point, the only thing I don't like about the current L10N api is that it's async (well it has to be) and I think I had problems importing modules after the localization files are loaded, I don't remember quite well.

Any suggestions on this @nt1m?

I don't know much about l10n on Firefox OS, sorry.
