SF Patch # 103839 byt dougfort: Allow ';' in attributes

sgmllib does not recognize HTML attributes containing the semicolon
';' character. This may be in accordance with the HTML spec, but there
are sites that use it (excite.com) and the browsers I regularly use
(IE5, Netscape, Opera) all handle it. Doug Fort Downright Software LLC
