	* libgimp/gimpcolorarea.[ch]: finished new GimpColorArea widget which
	uses GimpRGB and handles DND and alpha channel.

	* libgimp/gimpcolorbutton.[ch]: use GimpColorArea. The API of the
	GimpColorButton has changed!

	* libgimp/gimpwidgets.[ch]: added temporary function
	gimp_color_update_uchar() to ease migration of plug-ins to GimpRGB.
	This function will go away.

	* plug-ins/script-fu/script-fu-scripts.c: use new GimpColorArea and
	GimpColorButton. Started to introduce GimpRGB color type. This change
	might have broken some of these plug-ins. This is work in progress.

	* libgimp/Makefile.am: added GimpColorArea and GimpColorButton to
	libgimpi.

	* app/gimpcontext.[ch]: added gimp_palette_get_[fore|back]ground()
	functions so the app can link against libgimp/gimpcolorbutton.o.
	These functions will go away.

	* app/gimpdnd.c: use a GimpColorArea for DND
