Sensor nodes can now report their sketch name and version to the gateway for informational purposes. Added class methods sendSketchName(), sendSketchVersion() and sendSketchInfo() that invokes the aforementioned as a convenience method. Sensor nodes report their sketch information to the gateway by calling sendSketchInfo(const char *name, const char *version) in the Arduino sketch setup() method after initializing the radio by invoking the Sensor::begin() method.
