8C63: Handle Food Item
The handler for the food and drink items (sprite IDs 50 to 57). 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 40 is added to the energy of the player in PlayerEnergy, up to a maximum of F0. The chicken is then redrawn by DrawChicken.
