Add meal production cost to the meal price list

It would be very handy if we were able to see all our meal costs right there on our meal prices page. This would allow us to quickly see all of our dish food cost margins in an organized list, quickly see what the meal price should be set to, sort them by this margin column, as well as copy and paste them into an excel sheet so that we can use this data (ie find our average dish margin, track this over time, etc.)
