1. Modify auditor.actor_usr_history DoB column in the same manner
as actor.usr to ensure consistent date truncation.
2. let update_auditors() recreate auditor.actor_usr_lifecycle for us.
3. Wrap the whole shebang in a PLPGSQL "DO" block so we can easily test
for the presence of optional reporter views that depend on actor.usr, so
they can be recreated as needed.
