Subject: [PATCH] Web: fix problems with title snarfer and unicode due to bug
 in HTMLParser in python 2.6+

Upstream bug: http://bugs.python.org/issue3932
Rather than override the unescape method with the patch posted, we just convert the page
text to unicode before passing it to the HTMLParser. UTF8 and Latin1 will eat just about
anything.
