Suggestion: Add total quantities on sale page

This is just a small suggestion. On trade pages at the bottom of each side of the proposal there's a table cell both for the total value of the cards and the number of cards involved in the trade. However, for orders it only displays the value and not the total quantity. It would be nice if the quantity were shown, however, since usually I double-check this number to make sure I'm not missing cards on a big trade/order, and its absence on the order page is definitely an inconvenience.
