Heavily refactor to get Node specific activities more generalized.  Settled on a sample activity that runs standalone, and a full-blown WebSocket application to receive request to add event listeners, gestures, and joints.  Created proxy library to match functionality in common/js/nuimotion-sockets.  In this fashion, you don't even know you're using sockets or what - all the logic is taken care of.  You just know you're using the NuiMotion plugin
