[Feature Request] Sort comments by old, new, highest rated or lowest

Just as the title says, I'd like to have the ability to let anyone (even non registered users) view the comments and organize them in these ways:

• Oldest comment at the top
• Newest comments at the top
• Highest upvoted/rated comment at the top
• Lowest rated/downvoted comment at the top

A lot of times the highest voted/rated comment is something very funny, very intelligent, etc and that's why it receives so many votes. Many other commenting systems have this ability and I believe it would attract even more people to this comment system.

Thank you for taking the time to read this request, have a wonderful day.
