Cooking should depend on Hunger and Thirst or none of them

[oniatus]

Cooking depends on Hunger at the moment.
Nearly all food items provide the FoodComponent from the Hunger module.

However, nearly all food items also provide the DrinkComponent from the Thirst module.

Activating Cooking only will not activate (or download) the Thirst module, leaving the player with a hunger-bar only.

It's likely that cooking will function without hunger or thirst but this is probably very pointless :) For consistency, we should add thirst to the dependencies which also would make the testing much easier.

Bumping this and adding it to new project board https://github.com/orgs/Terasology/projects/9 for @jellysnake :D

Likely outcome: Depend on a new "Sustenance" module that holds the shared functionality

In addition to adding a dependency to Thirst, FillingModifier needs to be adjusted to also fill the thirst bar based on the DrinkComponents filling value for the ingredients.
