Title: Add rel="nofollow" to links using parse_urls()

Should fix #5244.

I have an issue though with the `class` attributes passed to `output/url`: it doesn't seem to ever reach destination, and the class is not set for the link type (according to the URL's scheme).

Another issue (maybe coming from HTMLawed?) is that IRC links are prepended with "denied:". Probably a configuration setting somewhere.
