I18n helpers

[nofxx]

Way before DHH enum arrived there was a lot of solutions for this and one I took to maintain (AR pain) was Symbolize.

A nice feature I've ported from it is i18n helpers: _text to get the value translated quickly and _values to get all translations (good for drop down).

They are pretty cheap oneliners, but very handy (at least for my apps).
If you would like I'll create a pull request.

@nofxx Great suggestion, I definitely want to include this in v1.0.0. I'm planning to break the library down into some better modules, and I think this might include a separate I18n module. I'll keep this issue open to track and updates to this feature though..

Thanks for all your help and suggestions (across all my gems!) 😄 🍻
