Title: make blue arrow reflect remaining needed climb

BestCruiseTrack previously assumed goal arrival at current altitude. This change makes it assume arrival at user-specified safety altitude, which is much better for racing and little, if any, worse for non-racing. The only variable written by this new code is BestCruiseTrack, which is only used for orienting the blue arrow.
