Copyright and License Info

[yewang]

It seems that copyright and licensing info is missing from this repository.

I saw that your website (http://wgo.waltheri.net/) mentions that "All code is free, licensed under the MIT license". Is this true for all of the content in this repository?

I'm asking since I'm interested in using some of the wood grain and stone images in another open-source project (https://github.com/yewang/besogo).

In particular, I see that @atarnowsky contributed some image files in wgo.js/wgo/stones/. Are those also covered under the MIT license? What is appropriate copyright attribution for those files (i.e., should I attribute these to @atarnowsky)?
