 Description   

Currently NodeUtils do not provide any support for queries returning rows rather then nodes and conversion of their search results to more widely used node iterators. Attached patch adds support for iterating over row iterators and their on the fly wrapping into node iterators.

QueryUtil should be also updated to add support for such queries, e.g. like:

        Session session = MgnlContext.getJCRSession(workspace);
        QueryManager manager = session.getWorkspace().getQueryManager();
        Query query = manager.createQuery(statement, language);
        log.debug("selector:" + returnItemType + ":lang:" + language + ":query:" + statement);
        return NodeUtil.filterDuplicates(NodeUtil.filterParentNodeType(query.execute().getRows(), returnItemType));
