Updated OculusRiftEffect. Now it should work with the original OculusRif...

After the Oculus SDK was released i modified the OculusRiftEffect according to the documentation.
I'm still waiting for the devkit, but the distortion and the parameters are the same of the SDK demos.
It would be nice to port the Tuscany demo to Three.js but i don't know if their licence allow it. I will ask them.
As soon as i get my devkit i'll try to find a solution for the head tracking.
