Work on main multi player game logic

Couple of small bugs to fix:

* Add a request not found message to the request admin page.
* Fix the following phpcs

 81 | ERROR | The $_REQUEST super global must not be accessed directly; inject
    |       | the request_stack service and use
    |       | $stack->getCurrentRequest()->request->get('test') instead

Merging changes to review with Ron for testing. Individual games implemented and forms for multi-player players and rounds.
