Eliminated the global sharedQueue in favor of allowing each RKClient to own its a private queue. This eliminates problems where multiple clients are tracking reachability notifications and mutating the suspension state on a single queue. If you want to use a single queue across multiple RKClient instances, you can assign a single queue to both and worry about suspension and reachability yourself. fixes #278
