Duplicate Light Shader Nodes in a Same Way as You Duplicate Material Nodes

When you create a shader nodes for lamp objects, it is missing the functions we have with normal shaders.

Those are "fake user" "new material" and "unlink data-block".

Basically it seems that every light object shader nodes are having their unique nodes for some reason. I am thinking this to be bit un-intuitive, because you cannot very easily link the shader nodes you used in some other light source and also now you would have to edit the nodes separately to every light object.

I don't know any real reason why should the light nodes behave differently compared to the shader nodes here.
