New default server settings for factions in multiplayer

Pay to win with multiple alt accounts can be easily abused and it is an open secret in the SE community, especially on official servers with a player limit of 16 but no faction member limit. You can have 11 members 20+ alts in one faction.

One can simply register a new steam account, purchase a basic space engineer game and transfer the PCU to a dummy account. Making it unfair for other players and problematic for admins to proof it. Because one can simply use a second computer or game streaming service to avoid IP tracking.

I propose to following:

1. Member limit per faction

The default number should be half of the server player limit. (Can be changed in world settings page)

2. Faction diplomacy.

Player Faction to player faction peace should have a time limit of 1 hour (by default and can be changed in world settings), a warning message will show up on the player screen 5 mins before peace expiry and ask for 1 hour extension.

This allows trade activity between players but can stop players from creating dummy factions and link them together.

3. SUS spawn formula

This is a bit tricky and maybe challenging to implement. Player faction grids in close distance with other player faction grids will spawn SUS after 1 hour.

This will discourage dummy factions from building together. At the same time a PvP / trade activity lasting longer than 1 hour deserves an SUS.

4. Player faction PCU transfer limit

Ban PCU transfer between player factions.

(Unless it is admin or via a trade contract which does not exist yet, see economy 2 update suggestion)

Players with no faction can transfer PCU to players with no faction.

Players in the same faction can ONLY transfer PCU within the faction.
