User Identifier into comment answer

[allanalves23]

Its necessary change comment answers query to add the user identifier with lockup pipeline stage.

So, its very interesting add flags indicating if user is the article (comment's article) author, Coder Mind user (not article admins, just another Coder Mind user) or the normal reader.

Before this, maybe its necessary add one field in comment schema, like #1, for identify and insert the ID (identifier) when the author answers the comment.

For this its necessary change save answer resource too, for include the user identifier.
