Randoms Part 1 and also Corn - Random object sprites and corn tank changes. (#19975)

Added new sprites for random objects for everything in random/clothing,
/food, /loot, /medical, and /misc.
Also got distracted and changed how the corn oil/cooking oil tank looks
and how much reagent it holds. Now looks like the rest of the reagent
tanks and holds the same amount of liquid, 1000u.
