Subject: * Change meta tags to use html entity-escaped text for values, so
 that   quotes and such can be represented in title tags. * Depend and
 build-depend on HTML::Parser for HTML::Entities which is used   for the
 above. * Make --rebuild also cause --aggregate to re-download and write
 aggregated   pages. * Avoid outputting duplicate meta info. * Include title
 metadata on aggregated posts for capitalised and un-munged   titles.
