[Bf-cycles] Controlling eflection in glass shader

[Agustin Benavidez]

Yeah, with py files or whatever that gives you easy access at the most
common shaders you use every day, a mix between glossy and diffuse is going
to be probably in at least 50% of your scenes.
I am talking just like the default python templates in the text editor,
would be nice to have some default group presets.

Brecht, if you would have to modify the code with MINIMAL invasion/changes
to enable this in a proper way, what you would change? just throw a rough
idea, perhaps i can give it a try.
Some thoughts:
- Perhaps flag groups to shows up if only a header mode is set, like cycles
render
- Let the user define where/create a menu/submenu category
- I'm tired, have to go to the bed now :/

Cheers
Agus.
