Invert Color Cycles Node

Browse Source 
as with the HSV node the OSL code is relying on the (yet to be implemented) autorename.

Also the svm code could use mix (svm_lerp) instead:
 32 . float3 color_inv = make_float3(1.0f, 1.0f, 1.0f) - color;
 35 . . stack_store_float3(stack, out_color, svm_lerp(color_inv, color, factor));

I have a feeling that each node 'program' should have the least program as possible. I'll see with Brecht later.
But overall I don't know if that's any fast. And apart from that I think we will need this kind of function to move to a library if multiple functions linked in are not a problem.
