Sabre Wulf: Routine at B1B7

B1B7: Start Turn

Used by the routine at InitialiseGame. Sets up the delays at the start of a turn of a player, removes any orchid effect, takes one life from the player and displays the new number of lives. The start-of-turn delay (GameDelayTimer) is also what flashes the score label of the player (see GamePlayEntry).
