ircbot: irc.ignore_channels config option

In some circumstances the user might want to turn the bot into a pure
logbot for some channels. This can now be achieved by adding that
channel to the irc.ignore_channels config key, that makes the bot ignore
all PRIVMSG to that channel (note that notices and service messages such
as joins and parts are still acted on, just like for irc.ignore_users).
