Expose each Campfire user as a separate IRC nick

[jrk]

The Campfire-IRC bridge would feel much more native if each Campfire message were relayed to IRC from a nick dedicated to the originating user (rather than sending all from a single bot, prefixed with the Campfire-side username).

Structurally, this would seem to require refactoring the current design---where the relay is built into the IRC client, which contains the Campfire client as a slave---into a single top-level centralized relay agent, which contains multiple IRC clients (and one or more Campfire clients) as slaves.

Pretty ambitious - I love the idea. It would make tab completion work, too. In fact it'd be nice if nick: message was translated to Campfire Nick: message when going from irc => Campfire.
