Adds some flags for food
Currently this has 0 effect on the game, but it may be used later for fun stuff (like soups spilling when dropped, or a carnivore mutation which only allows you to eat meat)
Added a food_flags variable to food items
-
Currently used flags: FOOD_MEAT, FOOD_ANIMAL (food containing animal products - anything that vegans won't eat, basically), FOOD_SWEET, FOOD_LIQUID (soups)
-
Assigned these flags to (hopefully) all the food items
-
Removed a duplicate instance of cracker
