More Hydroponics content, mostly!

-Added pumpkin pie and slices. Made with 5 milk, 5 sugar, 1 pumpkin, 1 flour, 1 egg.
-Added carved pumpkins/jackolanterns. Carve them with any of the usual things you use to carve things. They work similarly to hardhats.
-Eating corn now makes corn cobs. Carve them with a saw, a knife, or a hatchet to make a corncob pipe. Set up class for smoking pipes to make it easy for others to add more pipes as desired.
-Added the bit of transparency to biohelmets that they were always supposed to have, fixed the scientist helmet being over too far by 1 pixel when facing right (OCD)
