	* app/widgets/gimppaletteview.[ch]: added "entry-clicked" and
	"color-dropped" signals. Completely handle color DND. Cleanup.

	* app/core/gimpmarshal.list: marshallers for above signals.

	* app/widgets/gimppaletteeditor.[ch]: chopped and reassembled.
	Remove tons of code and use a GimpPaletteView instead of the
	deprecated GtkPreview. Addresses bug #102204.
