Add an event handler for the FaviconChanged event. The FaviconChanged event is raised when the favicon

had a different URL then the previous URL. The FaviconChanged event will be raised for first navigating to a new document, whether or not a document declares a Favicon in HTML if the favicon is different from the previous fav icon. The event will be raised again if a favicon is declared in its HTML or has script to set its favicon. The favicon information can then be retrieved with GetFavicon and FaviconUri.
