feat(tournament): auto-join external tournaments and publish created ones (#77)

Official bots now poll the external tournament server and auto-join every
created tournament with the hardest bot (expert). Tournaments created in
NowChessSystems are forwarded to the native tournament server so the bots
can see and join them.
