Apparently having multiple hooks on the same thing is just horribly
broken, even though we do it in other places. This only fixes the issue
on connecting as that one is the most severe, but the other cases will
need to be fixed as well (or the underlying issue preventing it from
working needs to be fixed).
- Now possible to use the bot without it having a registered account by
blanking NICKSERV_IDENTIFY_COMMAND
- Now possible to configure who ChanServ is as well as the command it
uses to op up in channel (blank to prevent it from auto-opping).
Example configuration provided for undernet
- Properly autojoin channels even if there isn't an MOTD
