remove unimplemented bang_trigger() and replace with bang_trigger_at(n) 

normally we operate on TriggerPtr's which are a safe way to track
 trigger lifetime, safely modify their properties, and launch them.

bang_trigger_at() is a convenience function to look up a trigger by index,
 and launch it, in one step.  Potentially useful for control surfaces.
