Daniel Larimer 87d3d1a198 Update API and remove SPAM 
subscribe_to_objects now returns the initial value of the objects, this
makes it easy for someone to fetch and subscribe in a single atomic step
rather than having to call get and then subscribe which could lead to
some inconsistencies if the object was modified after get but before
subscribe.
