Title: Session Checking & Readme

When having a session_start() in your own code the session_start() in facebook.php would fire again, which would result in sending the headers again. This gives warnings in the logs, this code fixes the if statement.

I also updated the readme file, it says 'require' which could better be changed to require_once to prevent multiple inclusions. It's small detail however..
