Fixed: Friendly monsters could still be killed by splash damage even with...

This fixes a small oversight with sv_shootthroughallies in which splash damage could still hurt and kill your friendly monsters. Now when the flag is set to true, friendly monsters will be bounced around unharmed the same way that teammates are when they are hit by splash damage. Setting teamdamage above zero will cause them to take damage which is consistent with players. Friendly monsters can be telefragged so you won't get blocked by them either.
