Kitchen additions

Please add: obj/machinery/cooker/cerealmaker,
obj/machinery/cooker/foodgrill, /obj/machinery/cooking/candy, and
/obj/machinery/cooking/oven to the map.  Adds those items.  Also,
/obj/machinery/icemachine  Adds a lot of foods.  Eating monkey cubes now
results in disaster and pain.  There's probably!  A lot of stuff broken
but it totally compiles and honestly, the only broken stuff I can find
is a lack of idiocy checks (So you can grill cerealized cardboard and
turn it into a sandwich a mile high and stuff like that).  I think Para
actually removed the idiot-checks to make cooking more fun, so.  I kind
of approve of that.  Yes.
