Jeff Dairiki f48eda6ee2 Restore compatibility with mistune==0.8.4
The latest release version of Lektor is 3.3.4.  It does not include
the support for `mistune>=2.0` that has made it into the `master`
branch of Lektor, thus it pins `mistune<2`.

This commit restores compatibility with older versions of
mistune.  (That compatibility was broken by 3fcd062.)
