Added a ping watchdog, a secondary failsafe mechanism reconnecting device when a certain host is not reachable. This is needed because in some very rare cases users reports that devices are not able to reconnect to wifi after connection in lost (despite of handling disconnect even in code.... for me it's working, but still)
