List parent folder ("..") in document listing

Suggestion from Bart:

public SortableDocumentsProvider(JcrNodeModel model) {
this.folder = new Folder(model);
setSort("name", true);

resources = folder.getSubFoldersAndDocuments();
Folder parentFolder = folder.getParentFolder();
if (parentFolder != null)

{ resources.add(parentFolder); }

}

public Iterator<NodeModelWrapper> iterator(int first, int count)

{ sortResources(); List<NodeModelWrapper> list = Collections.unmodifiableList(resources.subList(first, first + count)); return list.iterator(); }

public IModel model(Object object)

{ return (NodeModelWrapper) object; }

public int size()

{ return resources.size(); }
