DJ-Catalog2: minimum quantities for products and units incrementals

Would be a good idea to define in every product a minimum quantity for selling this product.
As well, would be great to be able to define an incremental number for selling a product, for instance, we could show the price for a bottle of wine, but the customer just could buy a 6bottle box, or 2x 6bottle box, or any other incremental.
