Änderung der Verabeitung von ContentBundles in RelatedLinks

Durch Einführung und Verwendung von ContentItemXMLRenderer weerden ContentBundles bei der Erzeugung der XML-Ausgabe zur ausgehandelten Sprache aufgelöst und statt des ContentBundles dieses neue Objekt ausgeben. Es ist eine API-Änderung nötig gewesen: in DomainObjectTraversal.java mußte die walk()-Methode protected markiert werden. (Dateien vergessen hinzuzufügen.) git-svn-id: https://svn.libreccm.org/ccm/trunk@320 8810af33-2d31-482b-a856-94f89814c4df
