Create an option to order the comments on their post time

It'd be nice to have an option to change the order of the comments/captions on an image; instead of being based on the highest rating being first, there could be an option to order it based on the time (newest being first).

It would make me moan like an elderly orgasmic sheep if we had this, and it would solve the problem of the good-but-new captions being at the bottom.
