Add food items to the food cart.

The poor food cart is still empty after all this time, so I figured I could add some food item spawns to it. Better get there quick though, before they spoil!

The kitchen unit can have: 0-2 burgers, 0-2 cheeseburgers, 0-1 sloppy joes, 0-2 fries, 0-1 packs of bacon, and (with 1% chance) the horrifying collection of human burgers. (Post-cataclysm survivor making use of the stove, or Sweeny Todd's Burger Cart? You decide!)

The minifridge can contain various condiments. Any combination of: ketchup, mustard, mayo, pickles, onions, lettuce, tomato, and cheese. Since vehicles come with minifridges on, these might last longer than the meat.
