Do not allow players to login if server is overloaded

[someniatko]

We all know, that server cannot hold on with 6K+ players. And instead of comfort gameplay, everybody experiences large delays (lags) in combat, chat, trading whatever.
But there is an alternative - set up the "critical point", at which server does not accept any new log-ins.
There will be some displeased players though, but, on the other hand, the remaining won't have any lags.

Deal with it.
