	Bug 553585 – Add orientation API to GtkRuler

	* gtk/gtkruler.[ch]: implement the GtkOrientable interface and
	swallow all code from GtkHRuler and GtkVRuler. Add gtk_ruler_new()
	which takes a GtkOrientation argument.

	* gtk/gtkhruler.c
	* gtk/gtkvruler.c: remove all code except the constructor and
	call gtk_orientable_set_orientation() in init().

	* gtk/gtk.symbols: add gtk_ruler_new().
