bot: add a bunch of event attrs related to msgs

- event.addressed - msg started with 'bot: '
- event.original_msg - the pub/privmsg
- event.addressed_msg - pub/privmsg minus 'bot: '
- event.sender_nick - nick of event.source
- event.sent_location - channel or nick of event.source
- event.in_privmsg - if the event was in a privmsg or not
