Please add asKeyIterator for queries

[GoogleCodeExporter]

Appengine 1.4.0 brings async queries support behind the scenes.
This support only works with Iterators result sets.

/**
     * Returns key iterator.
     * 
     * @return Iterator of keys.
     */
    public Iterator<Key> asKeyIterator() {
        query.setKeysOnly();
        final Iterator<Entity> entityIterator = asEntityIterator();
        return new Iterator<Key>() {
            public void remove() {
                entityIterator.remove();
            }

            public Key next() {
                return entityIterator.next().getKey();
            }

            public boolean hasNext() {
                return entityIterator.hasNext();
            }
        };
    }
