color-tools HSL-to-RGB saturation bug fix.rb

# The bug below has been fixed in color 1.4 which is 
# the successor to color-tools 1.3.0
#
# There's a bug in color-tools when converting HSL to RGB for desaturated
# colors. It doesn't multiple the lightness value by 255, so every resulting
# set of RGB values ends up being (1,1,1). This monkeypatch fixes it.
