Added preliminary body temperature system. If the player is cold, being near a source of heat or running around or breaking blocks will help to increase their body temperature. When cold, hunger decreases much faster. When a player is warm, running around and breaking blocks can overheat them. Players can cool down by having a thirst level above 500 and/or by standing in water. Wearing leather armour makes players warm up faster. Becomes unmanageable at world extremes, such as the equator or the poles.
