	* app/gimpsignal.[ch]: new GimpSignalType gimp_sigtype_int_int_int.

	* app/gimpcontext.[ch]: set/get colors as separate r/g/b values
	instead of a guchar[3] array.
	The "[foreground|background]_changed" signal handlers must have
	the following signature now:
	color_changed_callback (GimpContext *, gint, gint, gint, gpointer).
