	* nautilus-gdk-extensions.c: (nautilus_gdk_color_to_rgb): space,
	(nautilus_gdk_rgb_to_color): add function.. could be useful.
	* nautilus-gdk-extensions.h: add prototype.
	* nautilus-gtk-extensions.c: (rgb_to_hls): new internal function. converts
	from rgb to hls., (hls_to_rgb): from hls to rgb,
	(nautilus_gtk_style_shade): necassery magic to "shade a color by a given
	amount... All this was copied from panel.c which was in turn copied from
	gtk.
	* nautilus-gtk-extensions.h: add prototype.
