[DGD] terminology change

I called them "scheduled tasks" in a web page I set up for Hydra,
<http://www.dworkin.nl/hydra/> but callouts are actually more than
that.  They are much more essential than timed callbacks, and you
don't just pass a pointer to static data along but a bunch of
arguments that may contain complex datastructures which don't exist
anywhere else.

"Callout" is an odd name, but nothing else fits quite so well?
