- fix the binding of listeners on XMLHttpRequest to always use the
addEventListener method. It does not make sense to change it to
attachEvent as it is about binding listeners on DOM elements.
- fix the feature detection for the event binding on DOM elements:
- the attachEvent and addEventListener methods are on DOM elements,
not on the document object
- the standard method should be preferred in IE versions supporting
both methods
- avoid JS errors when XMLHttpRequest is not defined by avoiding to
override its open method when the object is not there (old IE versions
will still not intercept ajax calls though)
