	* app/base/colorize.[ch]: changed the range of the "lightness"
	parameter to [-100..+100], where -100 results in pure black and
	+100 in pure white. Default to lightness == 0 so the initial
	transform changes just the colors while keeping the original
	lightness.

	* app/tools/gimpcolorizetool.[ch]: changed accordingly. Reordered
	the scales to be in HSL order.
