Add choice of whitepoint for the blackbody node
The blackbody node is currently hardcoded to sRGB D65. This means that 6500K is RGB1,1,1 aka white.
But real world lamps use something closer to D50 in terms of reference whitepoint. Which - you guessed it - means that 5000K corresponds to white.
It would be nice if we could have the option to input real world lamp specifications into Blender lamps.

It would also help if Blackbody could work with the scene's color management instead of always being sRGB.
