finished event arguments in wrong order

[matthewleon]

Your readme example contains the following code:

chain.on('finished', function(err, name) {
  console.log(name, "has finished.  Error:", err)
})

In reality, the callback will receive its arguments in the reverse order. Here is the relevant code (line 49 of the compiled index.js):

this.emit('finished', job.name, err);

So either the readme or the code has to change. Personally, I think the code should be changed to reflect the README, even though this might break some applications. Sending the error first is a very strong convention.

Ah, I did that because I didn't want to break compatibility. Let's make this crap correct for 1.0.
