Now reverts PHP to cgi handler if user removes suphp.
Now reverts PHP to cgi handler if user removes suphp.

Case EA-3714: This has 3 changes:
 1. Properly reverts to CGI Apache handler if SuPHP is removed
    while in use.
 2. Sends a notification to the administrator letting them know
    that they shouldn't have removed the handler.  This depends
    on CPANEL-1688 to be merged into 11.52/11.54.  Without this
    story, the notification will never be sent.
 3. No longer restarts Apache.  This should be done by the
    restarterv_httpd universal hook.
