35939: Handle Food Item
The handler for the food and drink items (sprite IDs 80 to 87). If the player is not touching the item then the colour of its cells is set by SetItemAttributes. When the player touches it the item is removed, the eating sound is queued (see SoundsEating), and 64 is added to the energy of the player in PlayerEnergy, up to a maximum of 240. The chicken is then redrawn by DrawChicken.
