Several Improvements After Sonoma

driver messages sent to lemon-pi will now play in the drivers ear, as well as displaying on screen
As you cross the line the race position shows .. until the predictive lap timer starts predicting
As a carfollowing you crosses the line, the predictive lap timer disappears for 10s and the following car's gap is shown
As the car goes on track, this is sent to the cloud
And .. it now works on tracks in forward and reverse directions
