Backport "server queue"

[izstas]

Please backport this (respectively 1829 and 1831) to MTA 1.0.4, I really want this feature now

I tried to port it manually (also I did small tweak - changed SERVER_UPDATE_INTERVAL from constant to setting in coreconfig.xml but it maybe not really needed) and it looks like working, excepting that I got timeout after "Entering the game". I think it's not bug, just network library disallows join with modified client.

Thanks
