This should prevent breaking out of the search to grep /etc/shadow or similar shenanigans.

This allows including the EFnet logs in the search of the new hackint channels while still keeping the log files separate.

This introduces an up to 10 second delay if a SIGINT is received just after changing the config. I can't be bothered to integrate this with Storage.run and overly complicate things.

Per RFC 7235, the realm value can be a quoted-string. That's defined in RFC 7230 and can contain HTAB or SP and up except for the double quote, backslash, or DEL. (Double quote and backslash could be escaped by backslash, but I won't bother with implementing that until it's needed.)

IRCClientProtocol.channels gets updated on the KICK, so it will naturally appear in channelsToJoin (as long as it's still in the config).
