SetThingTimer
Sets a timer event for a thing. This is similar to a timer set by SetTimer(), but it is treated
as an event and the timer message will be sent
to all of the thing's associated cogs. Only a cog that receives the thing's messages can
set a thing timer for the thing. The timer will not be stopped if the thing dies. Syntax:
SetThingTimer(thing, flex_delay);
To stop the thing timer, use:
SetThingTimer(same_thing, 0);
