Add a timeout for Samsung since we can probably assume if the TV on the same network doesnt reply in 3 seconds that its probably off.  Added events for Nest to give you twilio, pushover and/or voice notifications (configurable in config) if your smoke detectors go off.  Dont destroy Nest dom nodes if youre just changing states.  Also add target temp to Nest so its more clear.  Minor cleanup, bug fixes and slight performance tweaks
