Subject: meta: Generate meta description tags even when the html scrubber is
 enabled.

Unlike generic meta foo tags, meta description is known to be safe, so can
be special cased to be allowed despite the html scrubber. This makes meta
description much more useful, since it is otherwise limited to being used
by other plugins like map.
