Floats in position
Homes in on anything within it's radius (default is 160)
Impact with solid objects makes it explode with Etherian Stasis Energy effect
Damage affects other gords, does knockback
Can be shot, 1 hit one kill.

splashDamage and splashRadius - explosion size and damage
radius - how close someone has to be to go after them
speed - movement speed (default is 40)
target -fires them when explode

TODO:

	Allow to start dormant and wake up?
	Allow setting of health?
