Submitter/maintainer needed for w3c-linkchecker

[Ville Skyttä]

https://bugzilla.redhat.com/show_bug.cgi?id=627032

There is an (unofficial) ongoing review for my w3c-linkchecker
submission, but for the reasons outlined there, I'm not going to finish
the review process as the submitter nor will be maintaining it in
Fedora.  Feel free to pick it up as the submitter - unless someone does
that in a few weeks, I'll withdraw the review request.
