New build: .476 Heavy missile explosion size

Made the heavy explosions stay around for slightly longer (and also implemented stay-damage so they are more effective)

Fixed critical crash error from junk cards staying on 2nd new arcade game.

Made bearnoff not fly up from his own roars.

Slightly reduced the invulnerability frames on cluster bomblets

Made sure cluster bomblets deployed on each death.

Tweaked wave creation to favor targeting cities more and more as escalation and rounds tick by/up
