pkg_comments.php: Make comment timestamps link to the comment
As of today, there is no easy way to obtain a link to a specific comment on a package page. Many implementations of forums and comment systems today seem to follow a convention where a comment's timestamp is an unobtrusive link to the comment itself. Some examples are: - phpBB (e.g. bbs.archlinux.org) - GitHub - Disqus - Discourse This patch adopts this convention as well, by making the timestamp a link to the comment.
