2.91.5:

	Remove use of removed widgets.

	* examples/book/dialogs/fileselection:
	* examples/book/range_widgets/labeledoptionmenu.[h|cc]: Remove use of 
	removed widgets, which were hidden behind ifdefs. I think I only see this 
	now because of an ifdef error in recent gtkmm.
	* examples/others/rulers: Removed because Gtk::Ruler was removed from gtkmm.
	* examples/Makefile.am: Adapted.
