	* src/workbook-control-gui.c (wbcg_sheet_remove): Simplify.
	(wbcg_get_scg): Rename from wbcg_sheet_to_page_index and changed
	to return the scg only.  Make static.  All callers changed.

	* src/workbook.c (workbook_sheet_remove_controls): Renamed from
	workbook_sheet_hide_controls.
	(cb_sheet_visibility_change): Remove.  The workbook doesn't care
	about sheet visibility.

	* src/workbook-control-gui.c (wbcg_sheet_add): Set
	SHEET_CONTROL_GUI here.  Do everything here for invisible sheets
	too, but hide the table widget.  Attach signals for visibility
	[new] and sheet tabs here, not in wbcg_sheet_focus.
	(disconnect_sheet_signals): Take an extra argument to control
	whether to clear all signals or just those for the active sheet.
	All callers changed.
	(cb_sheet_label_button_press): Use the scg for data and simplify.
	(wbcg_sheet_remove_all): Disconnect signals for all sheets.  Use
	gtk_widget_destroy to get rid of the page.
	(wbcg_page_index_to_sheet): Remove.  Expand left-over bits to
	callers.
	(wbcg_sheet_to_page_index): Simplify now that sheets are 1-1 with
	tabs.

	* src/sheet-control-gui.c (sheet_control_gui_new): Don't set
	SHEET_CONTROL_KEY here.

	* src/workbook-control-gui.c (SHEET_CONTROL_KEY): Move to here.
	* src/sheet-control-gui.h (SHEET_CONTROL_KEY): From here.
