New Troop:Berserker

The berserker is a armor plated warrior who is INSANE. He is a de troop that, when killed, rages all the units around him. He attacks with a big metal sword/axe.
This rages the troops, not casts a spell. So if a dragon were near him and the dragon then went across the base, it would remain raged. The length of the rage-up would be 10 seconds.
