Doesn't support current Font Awesome icon set

Yeah, this is a problem in that it also seems to override many other plugins’ loading of more recent versions of the FontAwesome library.

Would be great to have the option to load the latest version from CDN as well as an option to specify not to load the FontAwesome CSS locally to be used when other plugins are doing so. Or perhaps better yet, simply detect if it’s already loaded and don’t do so.
