Update for GData changes

Fixes the project for GData re-org, and removes references to a constant that no longer exists. Adds a user agent now that GData complains in the console if there isn't one. It appears that the GData update somehow changes the the calendar ID URLs that we get back ("calendars" instead of "allcalendars" IIRC), so I made the parsing more generic.
