Render README markdown in the browser

cgit had no markdown support of its own, so a readme was rendered
through an external python filter or not at all. Escaping the source
and formatting it in cgit.js keeps the work in the browser like the
blob highlighter, and the page stays readable as plain text without
scripting.
