Changes the hunger system in various ways. New hunger hud icons. Food w/o sugar can be loaded in snack vending machines by anyone. Adding two new var for mobs "satiety" and "metabolism efficiency". Rearranging datum/reagents, all "good" medical reagents are under datum/reagent/medicine/ and all food&drink reagents are under datum/reagent/consumable. Adding a pizza crate to cargo orders. Growns and cooked food are given vitamins while junk food are all given sugar. Removed some unnecessary code in Chemistry-Reagents.dm .
high satiety+fed = higher metabolism_efficiency, lower if starving. Sugar digested drains satiety and vitamin raises satiety. Negative satiety means faster nutrition drop. Positive high satiety means lower chance to spread viruses. metabolism efficiency affect metabolization speed of healing and damaging reagents and the efficiency of bodytemp stabilization via calory use.
