[feature/prune-users] Rework user_delete() functions_user.php

Browse Source 
user_delete now uses fewer queries to delete a set of users of size > 1 by
accepting an array of users rather than a single user at a time.  This required
changing the third parameter, however the function retains its former behavior
with the old-style parameters.
