        * kwq/KWQKHTMLPart.mm:
        (KWQKHTMLPart::setView): If setting the view to nil and we have a
	document, detach the document. This means that we are removing a
	frame from the tree, so we want to run it's onUnload handler now,
	rather than later when things are no longer fully hooked up.
