Product clone - optional image cloning

Cloning a product currently copies the images as part of the process. This submission makes image duplication a configurable option, which is enabled by default for backward compatibility.

The impetus behind this change is that products with large # images can take a very long time to clone. Given that you won't likely want the same images for 2 products, this allows you to turn off image duplication if your business process does not require it.
