Channel Material - 13

Today I added the feature to move the operators in the channel editor. Then I wanted to add a menu to the editor to make it possible to add operators. But I found out, I have never given the vector graphic editors that functionality. I will first have to extend the UI-toolkit again. I hope it won't be a big change, but I was quite sure I had done the necessary stuff in the past.

Then I will add the ability to connect the pins of the operators and have to add another operator (defining the Phong shader) and then should be able to define a very simple shader with this thing. So I guess I can soon start to actually implement the evaluation in the OpenGL-renderer and in my raytracer.
