Add the ability for the owner to order the comments/manage them from within the app

Please update the commenting function to enable the owner to drag/change the order of all comments, AND tie the owner's comments to the element over which they are anchored (perhaps by enabling comment management in the application?) so that the comments will always show up in the order that a wire frame is laid out (e.g. let's stop having new comments regarding items at the top of page be located at the bottom of the comments list just because someone forgot to add them until AFTER adding a whole page's worth of comments)
