Title: Add XDomainRequest to browser env too

I think [`XDomainRequest`](https://developer.mozilla.org/en-US/docs/Web/API/XDomainRequest) should be added to the browser environment.

It already is part of the `wsh` environment (see #264), but it might also appear in IE9- compatible code which I wouldn't classify as a `Windows Script Host` environment.
