* Close the PHP session for writing as early as possible in most AJAX
calls for those views
* Reduce the number of roundtrips to the server in both the Dashboard
and Calendar views by putting the data in our HTML response (this
makes a massive difference)
* Eliminated a couple of unneccessary AJAX calls
* Use lazy loading in full calendar
* Fixed a bug in the week view that only occurs near the end of the
week (date->gmdate bug!)
