AUI 1741 Browser specific HTML class is not identifying renderer and browser classes properly in IE11

Hey Jon

I am working on LPP-13668.

The issue is about IE 11 cannot be detected by AUI.

The issue is fixed in https://github.com/yui/yui3/pull/1050.

So I want to back it port to the version v3.11.0.

Please let me know if there are any issues.

Thanks
