+	* Images/common_outlineUnexpandable.tiff added.
+	* Images/GNUmakefile modified to install images
+	* Source/NSOutlineView.m modified to use new images.
+	Also made several fixes which should now make NSOutlineView
+	usable.  The graphics used are consistent with the look of
+	the outline view in the OPENSTEP Interface Builder classes
