Scripted Java objects now have a prototype that only has the
href() and renderSkin() functions, without all the other functions in Helma objectmodel Nodes that don't apply to Java objects. This was a problem because it "covered" methods in the Java objects with the same name, e.g. list(), delete() etc.
