Title: Recognize .mdwn files as Markdown

`.mdwn` is (if you don’t use any hacks) the only supported Markdown extension of the [ikiwiki][] wiki system. (No, it’s not configurable.) Since ikiwiki is quite popular for Git and Markdown based wikis, we should support its Markdown file extension.

See also [the ikiwiki mdwn plugin][mdwn].
