[] adding new foods via JSON configs

@progwml6 That's in the TODO.md. This checklist is separate and exists so that we can be sure we didn't forget anything that's in the configs.

Also, the rotting stuff should be removed from the config, as it's never been functional, even in 1.6.4.

Closing, fairly sure all the config options are working as intended.
