restrict spymasters to one per team and teams to min. 2 players

[a-powelson]

Server should prevent games from starting if

• there is more than one spymaster per team, OR
• either team has < 2 players

[a-powelson]

Guess this will depend on game mode too

yeah duet would be different; we can leave that for later though
and is it a requirement that each time has only one spymaster? if there are a lot of players it may make sense for their to be two or more collaborating

[a-powelson]

Fair point, there doesn’t necessarily need to only be one spymaster. Would we want to implement something in the future to let them collaborate then?
