Make Permban HTTPD Module Admin Only

[Wild1145]

I believe the current perm ban list HTTPD module is open to the public, but we need to probably consider locking it down to just admins. That is how TF Patches have handled it but I'm not sure what the rational behind this decision was.

I hope that @ZeroEpoch1969 @Telesphoreo or @robingall2910 might be able to give some guidance as to why this decision was made before we accept the request / reject the request.
