Make a wish #1: Servers

[Luc@s]

i see a lot of complains about autoteam, i dont think its that bad to be honest. sauerbraten has no autoteam or shuffle thing by default, and honestly it sucks. teams are never balanced (especially on ladder servers where people play for their score).
Allow shuffle team to be voted by default, and let autoteam move players only if a team is outnumbering another, if anything.

There are many things i'd like to see done about servers, but here is one that will require no work : make MAXCL 20 again.
