[Flickr APIs] license retrieve

I think it would be good for the future to have a method that
retrieves the license of the photos, or that this license info came in
the same xml of searching results. I would definitely feel better in
changing someone else's photos if I could assure that it uses some
license that allows Derivative Work.
