food logic cleanup

This fixes the end of week logic in regards to food so that the reported and actual amounts produced match each other. This change does mean that food production will be 1/3 of what it actually was (matching the reported amount). So we may need to tweak these numbers. @Pregmodder is there a good reason why we couldn't report produced food even if the food mod is off and then allow the sale of said produced food for profit? Currently there is no reason to have slaves work the farm if you don't have animal shows and food mod is off. This may eliminate some false reports about food not working.
