Rest memory issues to address #765

This upgrades the Atmosphere version to 2.0.9, it also changes the way we use the UUIDBroadcaster class so that the proper life cycle management (configure, start, stop) is utilized.   There was a comment in the code that the CV rest io bundle may interfere with how we are now telling Atmosphere to use the UUIDBroadcaster class, I did not see any issues, but I only enabled the CV bundle, I did not try using it.
