Added a new theme

A new theme submitted for your approval. I'm new at this pull request thing, so I'm not sure why all of the other themes are being pulled into this. The theme is called ray.css. It's based on the light version of the solarized color scheme and is generally lighter. I apologize for any inconvenience I'm causing and if you have any tips on not screwing up the pull request thing, I'd appreciate you pointing me in the right direction.
