[2020] Add kicking to ranked.

Being able to kick cheaters from your Ranked games would be nice! It would probably help reduce the amount of cheaters in Ranked. That's if the other players on the cheater's team actually Vote to Kick and don't keep them around for free elo. The MMR Rollback would help counter that. :)
