Expose clone to node operations list (also should work with VBO and etc.) w/patch

Here is a small patch to make possible mass node cloning. Works through direct saving nodes to DB (not prepopulate surely). Maybe batch processing is needed (can be easily adopted from core node module) but i've cloned hundred of CCK nodes without timeouts...
