Almost ready to move doc.php.net

Hi,

I've mostly set up doc.php.net at its new home. Please go ahead and take a look at https://doc-new.php.net -- you'll have to accept the self-signed certificate for now, but it will be behind the same CDN as the rest of the php.net sites when it takes over the throne from the current doc.php.net.

The phd documentation is currently not being generated, and I need to set up some rewrite rules for the old /tutorial/ URLs, but otherwise this should be functional. I ran out of time to work on it today, so the testing has been minimal. The translation status gets rebuilt every hour.

Feedback appreciated.

Jim
