I don't see the value. Consider the following two lines of SLIM or HAML:

```haml
.icon-camera
= fa_icon "camera"
```

Personally, I find the non-helper version to be nicer looking. And what benefit comes from the helper? Perhaps in the future the helper could be modified to write the icon hex code into the HTML so that the CSS could be slimmed down to just the `@font-face` directive? I'm not sure if that would be worthwhile IMO.

But I'm okay with the pull-request, as long as we aren't polluting the namespace ([see this comment](https://github.com/bokmann/font-awesome-rails/pull/30/files#r5581458)).
