Consider deprecating this gem in favor of font-awesome-rails

In an effort to avoid community confusion, I'd like to propose deprecating this gem in favor of [bokmann/font-awesome-rails](https://github.com/bokmann/font-awesome-rails). 

**Reasons:** The font-awesome-rails gem...

* also tracks Font-Awesome core very closely.
* has a test suite
* works with Rails 3.2 and Rails 4
* works when fonts are stored on a CDN (like CloudFront)
* similarly doesn't require sass or less, but 
* still works with sass imports (though if you're using Rails 4, you'll need to track sass-rails master at the moment)

If you're open to this, I suggest:

1. Clearing out the repository, but
1. Leave just a README with a pointer and explaination that font-awesome-rails should be used instead.

(I'm happy to submit a pull-request with this deprecation to save you time.)

Thoughts?
