Variable sized single use trigger that requires a key to trigger
targets.  Must be targeted at one or more entities.

"cnt"     if 1, leave a used key in the player's inventory (0 default).
"keyname" if set, this is the keyname of the item_key_custom which unlocks
        this entity.
"message" is printed when the trigger is touched without having the right key.
"noise1"  sound file for the "key required" sound (default is per worldtype).
"noise2"  sound file for the "key used" sound (default is per worldtype).
