extension tasklist not found

[chrkau]

It seems the tasklist extension is broken (or rather not available):

require 'commonmarker'

CommonMarker.render_html('foo', :DEFAULT, [:tasklist])

results in:

Traceback (most recent call last):
	2: from test.rb:3:in `<main>'

Yep, this documentation is mistaken. (Now fixed.) tasklist isn't actually an extension rendered by the underlying library. Thanks for the report.

Tasklist has been merged to cmark end of 2018 (github/cmark-gfm#94). I gave it a go to try and extend the options to add tasklist, but didn't get too far. Just posting this here for visibility if anyone competent wants to give it a try.

Thanks for the bump, @oliverguenther. I opened #94 to start looking into this.
