Wake Word Worky

Wake word has been implemented.  I have found it very convienent.  I don't want my bot responding when I'm not talking to it.  The logs have been greatly improved so its easy to see what is going on.  

In this session I named my bot Carl .   After 10 seconds of inactivity, carl will sleep - but he's always listening for his name.  Once he hears his name, he'll respond immediately.  From that point I don't need to constantly say Car.  I have his attention and he will respond to everything I say, until an uninterrupted 10 seconds of silence occurs, afterwhich he'll be back in sleep mode.

Good Morning Carl !
