Update jQuery to fix DOM tree leaks
Update jQuery to fix DOM tree leaks

jQuery was holding references in its cache to DOM elements that should
have been destroyed. DOM elements created by Bootstrap tooltips tended
to exhibit this behavior. The detached DOM trees could be seen by
comparing heap snapshots before and after browsing to web client views
which contain a HierarchyWidget.

The relevant fix in jQuery is likely:
https://github.com/jquery/jquery/commit/56bb677725b21415905e5c3eeb1e05be4480e780

This fix was first included in jQuery 2.2.0, but this commit pins to the
most recent 2.2.x version.
