The layout root is now kept alive via Document::m_layout_root. This will allow us to do more layout-related things inside the inner layer of LibHTML without reaching out to the HtmlView. I'd like to keep HtmlView at a slightly higher level, to prevent it from getting too complex. This patch also fixes accidental disconnection of the layout tree from the DOM after doing a layout tree rebuild. ~LayoutNode() now only unsets the DOM node's layout_node() if it's itself.
