added the solarized scheme to Kod.app

I wasn't the one to do it, all cred to @tripleonard for that! I just made the setup script.
If you look here https://github.com/tripleonard/kod-solarized/pull/3#issuecomment-4160080 I told him that I would do the pull request, with his permission of course!

And also, you did a great job with the colorscheme. I'm using it daily!
Take care
