Call ready callback with an error if login fails

[FrontierPsychiatrist]

Currently the only thing that happens is that an error message is printed on the screen.

New:

spotify.on({
  ready: function(err) {
    if(err) {
      console.log('Login failed: ', err);
    }
});

Would be great if you'd update the documentation to reflect the err being passed on http://www.node-spotify.com/api.html#spotify and especially the example on http://www.node-spotify.com/example.html

Thanks for the great work!

Yep, you're right, I'll update it. Thanks!

I've updated the example and made the documentation page (hopefully) more clear.
