PvP: Set Non-Random Teams in PvP

[Ek-Videogames]

New design by @JeroonBosch

Team selection mode ("The method at which teams are formed in PvP mode" on-hover):

• Player preference (current functionality, teams are formed upon round start based on preferences)
• Player chosen (functionality described below, teams are formed in the lobby)

Auto-balance teams threshold ("Ensure teams are equal before starting a round). Values:

• Off
• 1 (default value)
• 2
• 3

Choose team Pick a team to instantly join in the lobby. You're guaranteed to choose the picked up, and get access to the team chat. If auto-balance is on, grey out and make it unable to join a team that's already at it's limit.

"No preference" works a bit differently, it instantly places the team in either team (but only the team that has space).

Upon certain triggers (1. when a player leaves a server, 2. when a player leaves a team to join spectators, maybe more) reevaluate auto-balance and do a countdown in chat:

Server: Teams are imbalanced, automatically balancing the teams in 10 seconds...

10 seconds later it will switch random player(s) part of the full team to the less full team

Server: Teams have been balanced automatically. Switched players: [player A], [Player B]

Current implementation allows only for players to set a team preference. The teams are only actually assigned after round start.

TODO needs mockup and design on how to actually select a team.

Team selection modes that can be considered in the future:

• Force random (functions as if all players have "no preference" selected)
• Server assigned (server gives all players a team, players cannot switch.. probably needs more thinking and imo we can skip this and better allow players to police it with "Player chosen")
