- Now sends a CreateActivity request instead of a PublishSchema request to the server for already open activities, since the server reuses open activities for HTML-based clients anyway.

- Closes activities that have a keepOpenForSession="false" attribute when the page is navigated away from.

- Added support for sync ajax calls, for use with CloseActivity requests.

- Now doesn't send context to server on clicking a drilldown link if a different drillDownPage has been set.
