As of March 2017 the AWS Console UI has changed and you can no longer enter a 'versioning mode' described in my old post.
It seems now folder with versioned files can be deleted freely without restriction.

Previous Version of AWS Console
If you are using the AWS Management Console and you have versioning turned ON, you must be in 'versioning mode' to delete the folder. You enter 'versioning mode' by going to the top of the page and next to where it says 'Versions:' select the Show button. Then you can proceed to right-click and delete your folder. Hope this helps someone.
