Add food and water to logic

[tinyhoot]

Food and water are among the few things not currently randomised. While their recipes are best left alone for something like the hard mode in #10, they could function as ingredients even in a baseline randomiser.

Cooked fish has no added challenge without randomisation, so those would be skipped. However, cured fish and particularly the different types of water add an interesting and most importantly renewable/farmable resource to the logic. When's the last time you built a stillsuit?
