This patch based on
http://www.netadventure.net/~sburke/temp_html_tree/TreeBuilder.pm
should make it work properly with both HTML-Parser-2.25 and
HTML-Parser-3.00.

Sean is going to take over the HTML-Tree modules, so if he manages to
get his first release out soon, I should not have to rush out a
HTML-Parser-3.00 compatible HTML-Tree.
