Add logging config and move logging config options to it
Rename event.irc_message to event.content. This also only sets event.context if the IRC command is PRIVMSG. This allows for checking if an event is a message without relying on irc_* params, and anyways plugins can use event.irc_paramlist[-1] if they want the last param for non-message events.
