Adds way to get request headers

[orbiteleven]

Great idea! Tests perhaps?

Thanks for the PR!

What's the use case for this addition? It doesn't look like a standard method on the XMLHttpRequest interface and you can already check the request headers before returning a response e.g.

mock.get('http://localhost/api/user', function(req, res) {
  console.log(req.header('content-type'));
  return res;
});

@jameslnewell I agree - MockXMLHttpRequest should just implement the XMLHttpRequest interface, there's no practical need for this additional method.
