9443: Prepare Player
Used by the routines at StartGame and HandlerPlayerVanishing.
Sets up the player entity at Player for the start of a life. The template at PlayerTemplate is given the room that the player is in and the sprite ID of the character that was chosen in GameOptions, and is then copied over the player. Then the timer for the player appearing is set, the player is drawn (unless the number of lives is 03), the energy is refilled, and the chicken and the lives are drawn.
Work out the sprite ID to use.
