functions.inc.php:

- change list_admins() to use AdminHandler (code from list-admin.php)
  Note: this changes the return value format to include all details, 
  not only the usernames. Use array_keys(list_admins()) if you need
  the previous return format.
 
list-admin.php:
- replace code with a list_admins() call

list-domain.php:
- adopt to new list_admins() return value
