Display SKUs on product listings/pages

[ClaytonKing]

I used the beta feature to associate images with products. With an absence of documentation, I incorrectly assumed it would use product image filenames and SKUs as a first match process. I learned that was not the case, and some items in my store have the wrong photos attached to them.

I am now setting about deleting and associating the correct photos. The image filename matches the sku. However, the sku doesn't show anywhere but in the product list and in the item entry itself. It would be tremendously helpful if the sku could appear on the category/product pages so that one could simply reference it without drilling down to where it is entered.
