Request Errors do not return error, just null

[franky-continu]

Hi, in line 48, on the req.on('error') function handler. Could you please return an error?

    req.on('error', function(e) {
      console.log('problem with request: ' + e.message);
      if(callback) {
        callback(null);
      }
    });

This could return callback(e, null) or an object Job with the error code and messages like {status: 'error', error_code: e.code, error_message: e.message}

That way the code in the readme page which has the would always work with a proper return

var coconut = require('coconutjs');

coconut.createJob({
  'api_key': 'k-api-key',
  'conf': 'coconut.conf',
  'source': 'https://s3-eu-west-1.amazonaws.com/files.coconut.co/test.mp4',
  'vars': {'vid': 1234}
}, function(job) {
  if(job.status == 'ok') {
    console.log(job.id);
  } else {
    console.log(job.error_code);
    console.log(job.error_message);
  }
});

Thanking you in advance
