title: How to check if Font Awesome is loaded in web page with javascript?
body: <p>I need to check if a web page has Font Awesome in it.  If not I'm going to load it with javascript.  Kinda like how the facebook sdk checks to see if there is a script element containing the id "facebook-jssdk", if so it just returns (does nothing), if not it loads it.  I need to do that for Font Awesome.</p>
