Bart, unfortunately the ExtentHistory widget was not designed with JSAPI mode in
mind and so does not become aware of changes in the extents because the page
never submits in JSAPI mode.  The code in the ExtentHistory widget that tracks
the extents over time should be duplicated in the UpdateMap.php script and the
ExtentHistory widget will need a bunch of new javascript to connect to the JSAPI
MAP_EXTENTS_CHANGED event and activate/deactivate/navigate based on accumulating
the extents on the client side.  UpdateMap is required in case the page is
submitted for some reason.

This is a non-trivial amount of work unfortunately.
