Theme changed

I was tired of the Garland theme so I applied a very modest theme we use elsewhere. The theme was designed by Mathieu Petit-Clair and is now available through git. Do not be alarmed by the changed, it's only cosmetic (although I did optimize the site for performance and enabled login security). The reliable way to tell this is the right place is through the lock icon at the bottom right of your browser: the OpenID site should always use SSL on Koumbit.
