  speed - How fast it turns (degrees per second, default 30)
  dmg	- How much damage the laser does 10 times a second (default 5 = 50 points per second)
  wait  - How long the beam lasts, in seconds (default is 3)
  
  targetname - to use it
  target - What thing for it to be pointing at to start with
