Versioning Ember's docs


#1

I’m very interested in helping out with getting Ember’s docs versioned, something akin to how Symfony does it: http://symfony.com/doc/current/book/controller.html

There’s an github issue: https://github.com/emberjs/website/pull/481, but it’s gotten a bit stale. I’m hoping to spark some discussion here to get it moving.

Thoughts?
