Re wrote script

Altered  file completely  to ensure as best I can no errors  Noticed sometimes this  doesn't always install docs correctly  for some reason
Running  sudo apachectl -t -D DUMP_INCLUDES  does not reveal Include /etc/apache2/conf-enabled/apache2-doc.conf

To correct this Ive included a test function  to check if exists and then manually create this with the script

That should now solve issues
