	* app/core/gimppalette.[ch]: added GimpData::duplicate()
	implementation so read-only palettes can be edited again by
	duplicating them first.

	* app/gui/dialogs-constructors.c: pass the <Palettes>, not the
	<Gradients> menu identifier to the palette grid and tree view
	constructors (spotted by Tigert).
