* More consistent encoding of titles in rss and atom feeds. Don't use

ESCAPE=HTML for titles in the templates for these feeds, and instead
  escape the title going in to the template. Previously, the title was
  sometimes double-escaped in a feed (if set via meta title), and sometimes
  not (if set from the page filename).
* In the meta plugin, when a title is set, encode the html entities in it
  numerically. This works better in the current landscape of a rss spec that
  doesn't specify encoding, and variously broken feed consumers, according
  to <http://www.rssboard.org/rss-profile#data-types-characterdata>.
