Whitelisted slots for staff

[Havoc]

This feature request is primarily for I&A, but can also be implemented on other missions too.

 

In the last few weeks there have been moments where the server was completely or close to being filled up and that's when I had the idea for whitelisted slots for staff members. This way when a staff member wants to zeus or monitor the mission or server, they won't have to fill up a role that otherwise another player can join and leaves more room for players when the player count is building up.

I've already said this to Havoc in teamspeak but I should probably put it here as well: in I&A3 the server is limited to 60 players and there are 64 slots in the lobby.  There's thus always be 4 open slots which, in my opinion, negates the need for special slots for zeuses.  I&A4 will have this though.
