Title: Removed explicit protocol from image url

Although the https feature is great, in most cases I just want the image to be loaded using the protocol with which the page is loaded. I've made a small modification where the url no longer explicitly defines the protocol unless https is requested in the config. By default the url will now start with //www.gravatar.com.
