    Implement e_web_view_get_selection_html() and port a forgotten GtkHTML call to it
    
    WebKit does not have any native way of getting selected text or it's HTML
    so we need to provide our own implementation via the DOM API.
    
    There was a forgotten call to gtk_html_get_selection_html() in
    e-mail-reader-utils.c which was causing crash, ported to the new EWebView call now.
