Better test cleanup
Added/modified project files.
Rewrote RT tests, so that only one casper instance is asserting, failed tests make the suite fail now.
No need for cloning objects, notifySubscribers() will do. Also removes a bug when updates to indexed observables were POSTing twice.
Notification wires have a parent_id property now, makes grandchild wires possible.
Renamed method to show its exact purpose.
Added grandchild wires for updates on stats.
