Update jQuery from v3.2.1 to v3.3.1

Update jQuery from v3.2.1 to v3.3.1

Notable change:

- Ajax: In Safari, $.ajax() previously did not reject the
        Deferred if the XHR timed out. It now does, just as
        it previously did already in other browsers.

- Deferred: Fixed a memory leak with callback closures.

- All: Misc perf optimisations and removal of code that
       provided compat for browsers no longer supported.
