/*QUAKED fx_runner (0 0 1) (-8 -8 -8) (8 8 8) STARTOFF ONESHOT DAMAGE
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
