Don't blow up on 'No such nick/channel' and showErrors before blowing up!

• Don't blow up on err_nosuchnick, catch it and log it.
• It's a little easier to debug when we throw the pretty errors before blowing up.

👍 I'd like to see this as well, or at least some variation of it.

cjstewart88: all this extra code is unnecessary. The culprit is a single line self.emit('error', message);. This is what is making the client "blow up", as you say. All I did was change that line to self.emit('ircError', message);, and voila! It doesn't throw any more exceptions from IRC error responses.
