Subject: [PATCH] System/Libraries/Html/Renderer: Keep track of form element
 widgets

Save a pointer to the corresponding Gui widget for each form element as
an attribute in the @html_dom_node.

I'm not a fan of doing this, but it is probably one of the better
options considering the way things are currently implemented, and the
remaining work to be done.
