FIXED: Description can now be empty, thanks to @Jan.Erenberg for reporting this bug.
When checking for members, in the channel description members were shown randomly,
that means channel was edited every 30 seconds even if NO member connected or NO member disconnected.
Now (if everything works right) it should not spam the chat every 30 seconds, because members are now in the same order.
In this small update, I added channels, that if client is in he is considered as AFK client.
