Please add an action for additions within the "comment-metadata" div

[jwz]

I would like to add additional data to the ".comment-metadata" div, and there is no way to do that.

If I want to display the extra info for admins only, I can use the 'comment_text' filter, but that's a nasty hack, and obviously only shows up for users who are able to edit comments, so it doesn't help the general case.

I suggest adding an action just before or just after the call to edit_comment_link in class-walker-comment.php around line 460 (and also 360?)

Added a comment_metadata hook to filter the content of the comment metadata div, except for the edit link.

I worked on this during the Yoast Contributor Day.

I decided to make it a bit more general than just adding an action by using a filter instead. The first argument is the content of the comment metadata div, except for the edit link: so basically the time and date displayed as a direct link to the comment.

PR refreshed to fix the errors in the checks.
