USE_BUTTON - Won't fire unless player is in it and pressing use button (in addition to any other conditions)
FIRE_BUTTON - Won't fire unless player/NPC is in it and pressing fire button (in addition to any other conditions)
NPCONLY - only non-player NPCs can trigger this by touch
INACTIVE - Start off, has to be activated to be touchable/usable
MULTIPLE - multiple entities can touch this trigger in a single frame *and* if needed, the trigger can have a wait of > 0

"wait"		Seconds between triggerings, 0 default, number < 0 means one time only.
"random"	wait variance, default is 0
"delay"		how many seconds to wait to fire targets after tripped
"hiderange" As long as NPC's head is in this trigger, NPCs out of this hiderange cannot see him.  If you set an angle on the trigger, they're only hidden from enemies looking in that direction.  the player's crouch viewheight is 36, his standing viewheight is 54.  So a trigger thast should hide you when crouched but not standing should be 48 tall.
"target2"	The trigger will fire this only when the trigger has been activated and subsequently 'cleared'( once any of the conditions on the trigger have not been satisfied).  This will not fire the "target" more than once until the "target2" is fired (trigger field is 'cleared')
"speed"		How many seconds to wait to fire the target2, default is 1
"noise"		Sound to play when the trigger fires (plays at activator's origin)
"NPC_targetname"  Only the NPC with this NPC_targetname fires this trigger

Variable sized repeatable trigger.  Must be targeted at one or more entities.
so, the basic time between firing is a random time between
(wait - random) and (wait + random)

"team" - If set, only this team can trip this trigger
	0 - any
	1 - red
	2 - blue

"soundSet"	Ambient sound set to play when this trigger is activated

usetime		-	If specified (in milliseconds) along with the USE_BUTTON flag, will
				require a client to hold the use key for x amount of ms before firing.

Applicable only during Siege gametype:
teamuser	-	if 1, team 2 can't use this. If 2, team 1 can't use this.
siegetrig	-	if non-0, can only be activated by players carrying a misc_siege_item

teambalance	-	if non-0, is "owned" by the last team that activated. Can only be activated
				by the other team if the number of players on the other team inside	the
				trigger outnumber the number of players on the owning team inside the
				trigger.
target3		-	fire when activated by team1
target4		-	fire when activated by team2

idealclass	-	Can only be used by this class/these classes. You can specify use by
				multiple classes with the use of |, e.g.:
