Added PlayerStats class to monitor health and honor points. Added
PlayerStats parameter to WeaponWatcher class, so that shooting a Cat or
rabbit will now decrease player's honor points. Changed
PlayerMotionWatcher so that it uses a PlayerStats parameter. Therefore,
Cat can now damage player if player steps on it. Also had to add
PlayerStats parameter to PlayerLogger, Robot, powerup classes,
projectile classes.
