no longer alters its markup to render itself as disabled WICKET-4904

org.apache.wicket.markup.html.link.AbstractLink#getDisablingBehavior() is introduced. This method can return a non-null Behavior that can render markup for the Link in disabled mode.

By default The href and disabled attributes are still added/removed by AbstractLink as required.
