Subject: [PATCH] HTML-encode meta title, description, guid on output, but not
 in the pagestate

This makes them consistent with the rest of the meta keys. A wiki rebuild
will be needed on upgrade to this version; until the wiki is rebuilt,
double-escaping will occur in the titles of pages that have not changed.
