Fix Facebook badge snippet

Sometimes, when generating Facebook profile badges (http://www.facebook.com/facebook-widgets/profilebadges.php) that the resulting badge doesn't work correctly (broken link). To fix the error change the HTML generated in the following manner: substitute the http://badge.facebook.com/badge/1613451344..........png tag with http://www.facebook.com/badge/1613451344..........png and you are done.
