Title: Retain category, nsfw and license properties when photos are deleted from 500px

I don't think it makes sense to delete these properties when removing a photo from the publish service. These are user-set properties and I certainly would rather that once set I can be sure I won't have to go back and reset them if I choose to unpublish the photo and then republish it in a different account or something.
