- much better handling when users leave the game:
- put their hand in the discard pile
- if they played this round, put that card in the discard pile and remove them from the played players list
- if they were supposed to play this round, remove them from the players list
- if they were judge, return all played cards to players and move to the next judge
- if they weren't judge and were lower in judging order, fix the judge pointer
- add a goal to the game (8 points for now, hard-coded)
- keep track of which players are supposed to play this round so players joining and leaving don't affect the game progressing
