Added that ability for CouchdbStore to be observalbe with an EventSource from couchdb feeds. However, by default this will be off since there seems to be some form of performance hit where things no longer work in parrallel when this is on. Also, changed widgets to use the new couchdb store as observable if they need to. Added some print statements to debug what happens when. Also fixed extra deffered call in the ViewStreamer which was taking up a performance hit.
