Black and White level inputs to RGB Curves compositing node
This commit adds possibility to define black and white level of the
mapping curve of the RGB Curves node. This functionality is exactly
the same found in the Curves tool of the UV/Image Editor. It can be
used to extract wanted color ranges out of the input easily.
Thanks to Björn C. Schaefer for contribution!
