Reverse order playlist download. Last video first, first video last in numbering. Priority given to the previously last, now first video.

I second this! On youtube you can find many playlists that have it to where the uploader's most recent video, would be consider video number 01. on the playlist download. After the list is done downloading, I then find myself taking a while (depending on the amount of videos in the playlist) renumbering them so they'd be in order. It's a total pain. So please add an option to reverse a playlist download.
