Cycles: add light falloff node, with quadratic/linear/constant falloff and a
smoothing factor to reduce high values near the light.
http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/More#Light_Falloff
Note that this was already possible to do manually with the Ray Length, but
this adds a convenient node for it. This commit also makes the mapping node
min/max option work, fixing #31348.
