[Flightplan] Safety in default flightplan

Even the default basic flightplan should have more safety features enabled in an effort to reduce risks. 

 - it can be expected that the number of inexperienced users could grow especially since the ARDrone is supported
 - regulators become increasingly aware of "Drones" and every effort should be made not the have paparazzi mishaps

It is not obvious however what increases or actually decreases safety: e.g. killing a quad at the wrong location might prevent fly-away but might also create even higher risks. Therefore suggestions are welcome
