/*QUAKED target_steam (1 0 0) (-8 -8 -8) (8 8 8)
Creates a steam effect (particles w/ velocity in a line).

  speed = velocity of particles (default 50)
  count = number of particles (default 32)
  sounds = color of particles (default 8 for steam)
     the color range is from this color to this color + 6
  wait = seconds to run before stopping (overrides default
     value derived from func_timer)

  best way to use this is to tie it to a func_timer that "pokes"
  it every second (or however long you set the wait time, above)

  note that the width of the base is proportional to the speed
  good colors to use:
  6-9 - varying whites (darker to brighter)
  224 - sparks
  176 - blue water
  80  - brown water
  208 - slime
  232 - blood
