Ventanilla can now read the connections out of the relations object. It gives every block the uids of the connected blocks (block.input and block.output). The sensor objects are now compatible with johnny-five Sensor objects. To Register a sensor it is now only necesarry to send the sensor object that must contain a name (e.g. LD35) and a pin (e.g. "A0") and its Interface object, which should contain the uid of the interface (e.g. arduino board) which the sensor is connected with (this is no english anymore...)
