Finally, peas for the whole station. (#54573)

This PR brings three new plants, and 6 new food recipes into being. This is a combined port of Citadel-Station-13/Citadel-Station-13#12211 and Citadel-Station-13/Citadel-Station-13#12510, along with the fixes made along the way.

Laugh Peas contains 7% Laughter.
World Peas contains 10% Pax and Happiness, but takes at least 21 cycles to bear a harvest, by having a maturation time of 20.
Salad of Eden contains 3 units of Earthsblood, 5 units of Omnizine, and 2 units of Happiness, but requires one of every ambrosia leaf, as well as a world pea.

Credits to TripleZeta for the base peas sprite, and Stewydeadmike for the Laugh, World, and food sprites. Without them, the peas would have remained an ideasguy sort of deal.
