add "update" signal with the same signature as GimpImage::update(). 

2008-11-02  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpdrawablestack.[ch]: add "update" signal with the
	same signature as GimpImage::update(). Install handlers for the
	drawables' "update" and "visibility-changed" signals and emit
	"update" accordingly, item offsets taken into account. Also emit
	"update" when drawables are added, removed and reordered.

	* app/core/gimpimage.[ch]: remove handlers and tons of code that
	makes sure the image emits "update" on any of the above handled
	events and simply connect the layer and channel stacks' "update"
	signal to gimp_image_update().
