	* app/widgets/gimpgrideditor.[ch]: removed "grid_changed" signal.
	The user of GimpGridEditor can connect to notifications of the
	grid that is being edited. There is no need for a proxy signal.

	* app/core/gimpimage-grid.c (gimp_image_set_grid): don't exchange
	the image's grid object, it is part of the image. Copy all grid
	properties instead.

	* app/core/gimpimage-undo-push.c
	* app/gui/grid-dialog.c: changed accordingly.
