	* src/workbook-control-gui.c (cb_zoom_change): New function,
	extracted from wbcg_zoom_feedback.
	(wbcg_zoom_feedback): Remove zoom_feedback method.
	(wbcg_sheet_add): Don't attach to sheet notify signals here.
	(wbcg_sheet_focus): Do it here so we only watch one sheet at a
	time.
	(wbcg_sheet_remove, wbcg_sheet_remove_all): Disconnect here too.

	* src/sheet.c (sheet_set_zoom_factor): Make static and add
	zoom-factor property.  All callers changed.
