Ensured that the keyboard controls cannot be used if the game is started with the joystick's Fire button. Fixed use of incorrectly initialised zero page memory when moving the projectile - this could cause an enemy to be destroyed if the player stood by a wall and fired a projectile at it. Added a *TAPE call to the loader to ensure that DFS workspace is no longer in use.
