New Sanitizer Goes Live

The new sanitizer seems to work well (cuts the time required
to produce the Instiki Atom feed in half). Our strategy is to
use HTML5lib for <nowiki> content, but to use the new sanitizer
for content that has been processed by Maruku (and hence is
well-formed).

The one broken unit test won't affect us (since it dealt with
very malformed HTML).
