Rename Prototype Viktor to Professor Viktor

I know it is such a small detail but I think it fits the skin better to be renamed Professor Viktor instead of Prototype.

This is because I always thought of Viktor teaching a robotics class and the blackboard in the back of his splash art. Just some food for thought.
