These commands will create, destroy, and delay a countdown timer - 'addtimer'
to create, 'deltimer' to destroy and 'addtimercount' to delay it by the
specified number of ticks. For all three cases, the event label given is the
identifier of that timer. The timer runs on the character object that is
attached to the script (and I'm not sure what happens when nothing is
attached), and can have multiple instances. When the label is ran, it is ran
as if the player that the timer runs on has clicked the NPC.
When this timer runs out, a new execution thread will start in the specified
NPC object at the specified label. If no such label is found in the NPC
object, it will run as if clicked.
The ticks are given in 1/1000ths of a second.
