Title: Require sass/rails

This fixes the long-standing issue where font-awesome couldn't be found. I am not joking.

See [my investigation here](https://github.com/bokmann/font-awesome-rails/issues/88#issuecomment-46927257).

I believe similar fixes applied to other extensions will fix the problem there too.
