value -> markup. refactor check for a manual removal of the pre-auth role by the admin -- use a hidden form field instead. fix logic for password description. add a missing user message for registration when the pre-auth role is the auth user. fix broken query placeholders. remove unnecessary query that erroneously updated a user's login time when an admin validated their account. fix broken call to drupal_goto. fix up redirect array. use core's user mail functionality for resending validation emails. fix broken mail_alter implementation for admin validation emails.
