Changed code to reflect changes in tSquare.
Since Creator constructor args are no longer sent during the creation of a networked entity, changes had to be made.
Also made use of the new setNetObjects() in Entity.
switched over to NetVar.setEvent() instead of NetVar.event.
Increased buyable health and speed for zombies in Versus mode.
Hopefully fixed bug where zombies would have a target outside of it's current zone.
