A fix for window.location.origin in Internet Explorer

Internet Explorer does not have access to window.location.origin, which is a bummer because it is a pretty handy variable to have, but we can make it work with a fairly straight forward check because we access .origin;

if (!window.location.origin) {
  window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}

This should now have .origin set to what you would expect.
