8A15: Take Energy From Player
Used by the routine at HandlerHunchback.
Called when a boss has touched the player. It takes 10 (at TakeEnergyFromPlayer) or 08 (at TakeEnergyFromPlayer_Small) from PlayerEnergy. The chicken is then redrawn by DrawChicken, which returns to the caller. If the player did not have enough energy then the return address is discarded and LoseLife is used to take a life.
