Unmaintained Font Awesome Icons in Navbar for 2.1

Works Great. @akaasia I think you use "XenPorta" or you added first tab for some thing, if yes you must add the ID for the first tab in "extra.less".

Thanks works well except the What's new instead of the lightning bolt icon has a question mark icon. Not sure if there is a way to get the old icon back, anyway minor issue looks much better after this, thanks!
