cvs_mail_user() sends blank email when status=disabled

When a user's CVS account access status is set to disabled, they are sent an e-mail message, but the message is blank. The reason is that cvs_mail_user() doesn't have a case for CVS_DISABLED.

There are a few ways to fix this. One would be to just not send an e-mail message when an account is disabled. Another would be to send a message, but to tell the user they have been disabled. That's the approach I took, with code below. In all cases, just add the code after the similar code for the CVS_DECLINED condition.

In cvs_mail_user(), add this code:

      case CVS_DISABLED:
        $extra = $extra ? t('Reason:'). "\n". $extra ."\n\n" : '';
        $message = strtr($strings['cvs_disabled_email'], $message_variables);
        break; 

In cvs_settings_form(), add this code:

  $form['cvs_email_form']['cvs_disabled_email'] = array(
    '#title' => t('CVS account disabled e-mail message'),
    '#type' => 'textarea',
    '#default_value' => variable_get('cvs_disabled_email', $strings['cvs_disabled_email']),
    '#description' => t('The message to send to users whose accounts have been disabled.'),
  );

In _cvs_get_strings(), add this code:

  $strings['cvs_disabled_email'] = t('%account-name,
