Bring the docs from Codeplex

If I understand correctly, they will shutdown on Dec 17 2017 (1 month ago). The docs will be gone in this date!

Please bring the docs to some other place.

I went ahead and migrated them and created a pull request -> https://github.com/fstarred/xrns2xmod/pull/2

@01010111 Thank you for your contribution. I moved documentation to Wiki page and replaced image refs with fstarred, let me know if everything looks ok so I can close this issue
