	* src/sheet-control-gui.c (scg_set_current_object) : new. uses the
	  handy dandy unrealized signal on a SheetObject.  With code split from
	(scg_object_stop_editing) : here.
	(scg_mode_edit_object) : and here.
	* src/gnumeric-pane.c (cb_control_point_event) : so that we could use
	  it here.

	* src/sheet-control-gui.c (scg_mode_edit_object) :  fall back to edit
	  mode if the object is unrealized.

	* src/sheet-object.c (sheet_object_clear_sheet.) : merge some of the
	  nice features from finalize
	(sheet_object_finalize) : use sheet_object_clear_sheet.
	* src/sheet.c (sheet_destroy) : ditto.

	* src/gnumeric-pane.c (cb_control_point_event) : Make the copy
	  operation undo-able.
