Make a wish #1: Servers

[Vanquish]

Get rid of maximum clients (why was it even in place to the begin with, sauer and other games do not have this)

Sauer does. For some reason it's limited to players only though and there are unlimited spectator slots.
EDIT: Also quake does.

Expanding on that, I'd like to see servers that are in /mastermode 2 (match) to allow clients to connect in order to spectate (although are prohibited from joining the game), and for /mastermode 1 (private) to live up to its name and simply prevent people from joining the server.
