	* app/display/gimpdisplayoptions.[ch]: add new options object
	for the "no image" display appearance.

	* app/display/gimpdisplayshell.[ch]: keep one of them around.

	* app/display/gimpdisplayshell-appearance.[ch]: use the options
	object when the display is empty. Add guards against no image
	to some functions. Add gimp_display_shell_appearance_update()
	which sets all options according to the current display state
	(normal, fullscreen, no image).

	* app/actions/view-actions.c: don't allow to configure the GUI
	of the empty display.

	* app/display/gimpdisplayshell-callbacks.c: use the new appearance
	update function instead of doing it all here.

	* app/display/gimpdisplayshell-close.c
	* app/gui/gui-vtable.c: update the appearance when clearing or
	filling the display.

	* app/display/gimpdisplayshell-selection.c: forgot some guards
	against empty displays.
