* Added a node to convert a temperature in Kelvin to an RGB color. This can be used e.g. for lights, to easily find the right color temperature. = Some common temperatures = Candle light: 1500 Kelvin Sunset/Sunrise: 1850 Kelvin Studio lamps: 3200 Kelvin Horizon daylight: 5000 Kelvin Documentation: http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Blackbody Thanks to Philipp Oeser (lichtwerk), who essentially contributed to this with a patch! :) This is part of my GSoC 2013 project. SVN merge of r57424, r57487, r57507, r57525, r58253 and r58774
