/*-----------------------------------------------------------------------------
Used to give a script to an NPC when triggered. e.g. if an NPC walks through a
certain spot in the level could give him a script which will cause him to point
at a switch and fire off a dialog related to noticing the switch, shoot at 
switch etc.

If more than one script given, subsequent triggers will iterate through the list.
