Update for recent phpBB

[illwieckz]

Current code doesn't work with phpBB 3.3.

Here is a work-in-progress patch that doesn't work (see the comment):

         $config = $phpbb_container->get('config');
         set_config(null, null, null, $config);
         set_config_count(null, null, null, $config);

I also did an attempt by copy pasting code from phpBB's bin/phpbbcli.php and it didn't worked better. This is dark magic: the exact same code works if run by the phpbb script, not if run by the phpbbauth simplesamlphp plugin.
