Font Awesome 3.0.2

**I'm not sure this is ok**

I did all the possible things to ensure that everything went fine but I strongly encourage people interested in this pull request to test it in a production-like environment and in IE7 (in which I'm not interested at all).

I did almost all things listed here: https://github.com/seyhunak/twitter-bootstrap-rails/pull/485#issuecomment-11883383

```application.css``` after ```rake assets:precompile``` seems fine
```css
@font-face{font-family:"FontAwesome";src:url("/assets/fontawesome-webfont.eot?v=3.0.2");src:url("/a
ssets/fontawesome-webfont.eot?#iefix&v=3.0.2") format("embedded-opentype"),url("
/assets/fontawesome-webfont.woff?v=3.0.2") format("woff"),url("/assets/fontaweso
me-webfont.ttf?v=3.0.2") format("truetype");
```
