Fixed jQuery version to not use the buggy 2.1.1

- Specifically, our test files ocassionally did things like...
$(listOfElements[2]).click();
In 2.1.1, re-wrapping an element in jQuery worked for finding, but
you couldn't actually trigger events from it.

So just dropping down to 2.0.3 which is what we're using on the
main front-end apps, and works properly.
