 Updates the indego.state with state of mower, % lawn mowed, position, runtime, map coordinates.

 This function can be used instead of polling the status every couple of seconds: place one longpoll status request with a timeout of max. 300 seconds and the function will provide its return value when the status has been updated. As soon as an answer is received, the next longpoll status request can be placed. This should save traffic on both ends.
