Comment (by joostdevalk):

 In general, we should be adding `rel="nofollow ugc"` and not just
 `rel="ugc"`. While Google now supports `rel="ugc"`, other search engines
 only support `rel="nofollow"`, so we should really combine them and
 deliver both.

 Other than that the patch looks good @audrasjb but I'm wondering where
 you're hooking it to comment content? We also need to change the
 attributes on comment author links from `nofollow` to `nofollow ugc`.
