Updated hunger and thirst bar textures
Introducing new setting for hunger - a regeneration threshold. If an entity is below this hunger threshold, it will not regenerate health.
Introducing thirst system. Sprinting will consume thirst faster. For now, thirst has no adverse effects.
Filling for food and drink is now float not int.
Fixing loss of precision compilation error.
Tweaking thirst settings.
Hunger prevents healing only by natural healing of the entity, not just any healing.
Making sure the mods work in multi-player.
