	Fixed a 1.2 -> 2.0 regression that was forgotten:

	* app/widgets/widgets-enums.[ch]: added enum GimpColorPickState
	which can be one of { NEW, UPDATE }.

	* app/widgets/gimppaletteeditor.[ch]: changed #if 0'ed function
	gimp_palette_editor_update_color() to
	gimp_palette_editor_pick_color() and restored the functionality of
	creating/updating colors via this API

	Changed button_press handler to only edit the color on double
	click if it's really a double click on the same color.
	Fixes bug #141381.

	* app/tools/gimpcolorpickeroptions.[ch]: added boolean property
	"add-to-palette" and a GUI for it.

	* app/core/gimpmarshal.list
	* app/tools/gimpcolortool.[ch]: added a GimpColorPickState
	parameter to the "color_picked" signal. Pass NEW on button_press
	and UPDATE on motion.

	* app/tools/gimpcurvestool.c (gimp_curves_tool_color_picked)
	* app/tools/gimplevelstool.c (gimp_levels_tool_color_picked)
	* app/tools/gimppainttool.c (gimp_paint_tool_color_picked):
	changed accordingly

	* app/tools/gimpcolorpickertool.c (gimp_color_picker_tool_picked):
	If "add-to-palette" is TRUE, get the palette editor and call
	gimp_palette_editor_pick_color().
