/*
How the thing works:
- After channel is joined and NAMES list is got, send "channel query" signal
- "channel query" : add channel to server->quries lists
loop:
- Wait for NAMES list from all channels before doing anything else..
- After got the last NAMES list, start sending the queries ..
- find the query to send, check where server->queries list isn't NULL
(mode, who, banlist, ban exceptions, invite list)
- if not found anything -> all channels are synced
- send "command #chan1,#chan2,#chan3,.." command to server
- wait for reply from server, then check if it was last query to be sent to
server. If it was, send "channel sync" signal
- check if the reply was for last channel in the command list. If so,
goto loop
