	* app/tools/tools-enums.[ch]: added GIMP_COLOR_PICK_MODE_NONE to
	the GimpColorPickMode enum.

	* app/tools/gimpcolorpickeroptions.[ch]: removed "update-toolbox"
	property; the new enum value serves this role better.

	* app/tools/gimpcolorpickertool.c: handle the new enum value.

	* app/tools/gimpcolortool.c: default to GIMP_COLOR_PICK_MODE_NONE.
	Don't set a cursor modifier for this value. Fixes tool cursor for
	levels and curves tools.

	* app/tools/gimppainttool.[ch]: added a function to conveniently
	enable the color picker and set the pick mode at the same time.

	* app/tools/gimpairbrushtool.c
	* app/tools/gimppaintbrushtool.c
	* app/tools/gimppenciltool.c
	* app/tools/gimpsmudgetool.c: use the new function.

	* app/tools/gimperasertool.c: enabled color picking in the eraser
	tool but set the mode to GIMP_COLOR_PICK_MODE_BACKGROUND.
