New behaviour for command responses in general: FANTASY commands reply in channel as PRIVMSG, while all commands sent in PM reply as private notices.
- The old irc.called_by is now irc.called_in (PLACE last command was called)
- irc.called_by is now used to store the CALLER of the last command
- notice=True/False toggle is dropped from ServiceBot.call_cmd()
- New private=True/False option added to ServiceBot.reply() and irc.reply(), which controls whether replies should be sent privately or not.
