commandsUsage: unset <variable>
* in this example we have a var %testvar% we no longer need:
set testvar hops happily along
global testvar
%echo% %self.name% %testvar%
unset testvar
Unset removes the variable from the global variables of this trigger, or if not
found there, from the trigger.
Example: TSTAT 70
