[Old patch that hadn't been checked in.]

get_starttag_text():  New method.
        Return the text of the most recently parsed start tag, from
        the '<' to the '>' or '/'.  Not really useful for structure
        processing, but requested for Web-related use.  May also be
        useful for being able to re-generate the input from the parse
        events, but there's no equivalent for end tags.

attrfind:  Be a little more forgiving of unquoted attribute values.
