	Bug 455268 - Add gtk-enable-tooltips GtkSetting

	* gtk/gtk.symbols:
	* gtk/gtktoolbar.[ch] (gtk_toolbar_[gs]et_tooltips): deprecated.

	* gtk/gtksettings.c: introduce gtk-enable-tooltips XSetting.

	* gtk/gtktooltip.c (_gtk_tooltip_handle_event): take the newly
	introduced XSetting into account.

	* demos/gtk-demo/appwindow.c: don't use the now deprecated
	gtk_toolbar_set_tooltips().
