ZWave Application Status Message

This implements the application status message.  There is not a lot of documentation on this command class in the wild, but my Leviton DZS15-1LZ switches send these when switching on or off instead of using a HAIL or UPDATE message.  This class will schedule a poll for dynamic information after a default time or at a time which the device requests.  There might be cases where other types of devices want the controller to resend the last command rather then get dynamic info, implementing that would require quite a bit more logic and the way it is written now probably meets most use cases, also it gives us a starting point if other devices need to utilize this message. 
Absolutely. I'll get that taken care of in just a little bit.  Thanks Chris.
