Title: Added support for onload event (Required for Angular 1.3.0)

I noticed that after upgrading to AngularJS 1.3.0, XHR stopped working in my app under IE9. After looking at Angular's source, it looks like $httpBackend now uses the onload event rather than onreadystatechange. My change just dispatches a load event when the readystate changes to 4.
