API CHANGE Security::findAnAdministrator() no longer sets 'Email' and 'Password' properties on newly created members. Removed the $username and $password argments from the method.
ENHANCEMENT Member->requireDefaultRecords() no longer creates a default administrator based on $_REQUEST data. Moved functionality into Installer->install()
MINOR Security::findAnAdministrator() names any default administrators 'Default Admin' instead of 'Admin' (from r97478)
