IE8 incompatibility caused by fix #105

[gulima]

In Internet Explorer 8, Object.defineProperty() can be used only on DOM objects [1].
Calling this method on an "generic" object literal (like the xhrObject) throws an error that says object does not support this action, and the code execution is halted.
That way, jquery-typeahead is not compatible (when we need AJAX requests, at least) with IE8.
