this provides a somewhat unconfigurable (at the moment) feed module
which provides Atom and RSS feeds. entries are determined by symlinks to
content pages, because my core CMS usage is still more general and not
blog-like. the symlinks allow for arbitrarily adding entries as I see
fit.
this also moves core Markdown parser stuff to the library module, since
that's used by the feed as well as normal pages

moving this allows for per-instance customizations later, but that won't
be practical until serving styles from the instance dir is also allowed.
but, this sets the ground work and does allow for removing some styles
(e.g. if someone wanted to only allow 'plain').
also I still need to add the ability to present the themes list dynamically
the footnote extra expects to only parse one document over the Markup's
lifetime, and writes the footnotes to the bottom of every page that is
rendered (again assuming only one) with links back to the reference
having one parser for the entire app, naturally, introduced
ever-increasing footnote links and every footnote on the site showing up
on every page. this was not intended
in some light testing, doing this per-request has a nominal effect on
performance
