Farming fixes

[OgelGames]

This should be everything that needs fixes to be able to update farming:

• Undo change to cocoa, removing raw cocoa beans, so that it existing seeds don't become unplantable.
• Re-add peas and soy beans, also changed them into seeds, and made soy beans poison you if eaten.
• Adjust pie nutrition and recipe output to match the new textures, which look like 1/8 slices.

Also I added some old textures to pandorabox_textures because the new ones looked worse: https://github.com/pandorabox-io/pandorabox-textures/commit/0920dc3940910b5b151f42b05c5829a65d0784e2

Farmers and traders are updated too: https://github.com/pandorabox-io/mobs_npc/commit/6173ce9d66c29ed4a07746dfd02a564e2696b1f8 and https://github.com/pandorabox-io/mobs_npc/commit/00ea8d44218b18aa62b58c6d99de6be2b7bd7afb

And a PR for farming_nextgen is open too: https://github.com/berengma/farming_nextgen/pull/22
