Explicitly requiring i18n necessary?

I have included this gem a few places and have had to explicitly include the `//=require i18n` line in my application.js file in order to gain access to the `t` function on the I18n object. Otherwise, you have to get at the translations with syntax such as: `I18n.translations.en.etc.etc`. Could totally be some quirk on my setup (Rails, Angular) - but figured I would open a PR/Discussion in case this affected anyone else.

Cheers :)
