Created improved 404 page and cleaned up directory

-delete old, crappy 404 page to make way for new one
-instert new 404 page with graphic for hole in the internet
-change httpd.conf to reflect new 404 page name
-delete index.html that was outside of docroot folder and not being served by puppet
-add variable $doc_root to init.pp to account for ubuntu systems having different default DocumentRoot
fix bug in init.pp where first file resource didn't refer to anything

-removed the line telling puppet to make a backup, which was added to get a backup of the ./docroot dir when purged. This is default behavior of puppet and not required
bug fix for init.pp extra ','

-remove comma after the case selector variable for $doc_root value.
