Runs the specified effect, can also be targeted at an info_notnull to orient the effect

	STARTOFF - effect starts off, toggles on/off when used
	ONESHOT - effect fires only when used
	DAMAGE - does radius damage around effect every "delay" milliseonds

	"fxFile" - name of the effect file to play
	"target" - direction to aim the effect in, otherwise defaults to up
	"target2" - uses its target2 when the fx gets triggered
	"delay"  - how often to call the effect, don't over-do this ( default 200 )
	"random" - random amount of time to add to delay, ( default 0, 200 = 0ms to 200ms )
	"splashRadius" - only works when damage is checked ( default 16 )
	"splashDamage" - only works when damage is checked ( default 5 )
	"soundset"	- bmodel set to use, plays start sound when toggled on, loop sound while on ( doesn't play on a oneshot), and a stop sound when turned off

  ALT - uses slightly different shader, good if using two layers sort of close together

"radius" - outer radius of cloud layer, (default 2048)
"random" - inner radius of cloud layer, (default 128) only works for TUBE type
"wait" - adds curvature as it moves out to the edge of the layer.  ( default 0 ), 1 = small up, 3 = up more, -1 = small down, -3 = down more, etc.
