WebKit hits ASSERT when attempting to drag an image from an SVG

In the end, this seems to have been due to a lack of [DOMSVGImageElement _subresources], which I implemented.  In order to make it work, I also had to export DOMSVG symbols from WebCore, as well as teach WebKit how to copy over the DOMSVG* header files into it's PrivateHeaders.

I don't believe this statement is true.  It's possible for DRT to save pages as WebArchives now.  See the tests in the LayoutTests/webarchive/ directory.
