Title: Allow additional css classes to be applied using the data-css-class attribute.

This allows popular Bootstrap CSS like img-rounded or img-circle to be applied to the gravatar.

BTW, I really like the usefulness of your directive and plan on using it in my projects. It was pretty much a drop-in to AngularJS.
