Search for applied discount codes and view usages on the Discounts list page

[seanrockster]

Currently we cannot search for orders that have used a specific discount code.

It would be a nice feature if the Orders search included applied discount codes (an possibly product codes/skus?).

It would also be nice if the Discounts list had an additional column that indicated how many times the discount was applied, maybe even open up the infinite editor and display a list of those orders, maybe a print/export feature.

Keep up the good work!

Thanks.
