Use 2 decimal places for dollar values in store orders
Dollar values do not use 0's in decimals on the order page.
When I look at an order in admin view, if the price is an even amount (like $9.00) the decimals do not show up. If only one decimal is needed (like $9.50) then the 0 doesn't show up.
This needs to be configurable. We are in Japan without decimals, and you seem to have added this feature, and now my prices look ridiculous. There are no fractional Yen.
