  Log Message:
  -----------
  Added a new config::optional_child function

This is intended to replace uses of config::child that may fail, since we eventually want to get rid
of that ugly "invalid config" and the dreaded "Mandatory child missing yet untested for" error.

Both config::child and config::find_child had new optional throw-if-not-found behavior added, enabled
by an instance of config::throw_when_child_not_found.
