This adds some extra functions recently added to the float Maths Node. Not all functions have been ported over in this patch. Also: + Tidy up menu + Change node color to match other vector nodes, this helps distinguish vector and float nodes in the tree + Move shared OSL functions to new header node_math.h Reviewed By: brecht Differential Revision: https://developer.blender.org/D6713
