Title: Add support for the seamless attribute for iframes

Supporting the `seamless` attribute for iframes with a tiny bit of CSS is pretty simple so I think it should be implemented. I've added support, based on the patch here: http://trac.webkit.org/changeset/115773/trunk/Source/WebCore/css/html.css#file0
