First iteration of game physics - coding with TGB day 2

The emerging game physics looks better that I was expecting. There is a lot of things going on behind the scene: 

- tilting the ship depending on the current velocity and previous rotation,
- bouncing when trying to land on objects other than landing platform on when colliding,
- decreasing ship condition after each impact (not exposed to the GUI jet).

 The 'tilting' code so far is very simple:

function player::onUpdate()
{
    %desiredRotation = $player.getLinearVelocityX() ;
    %newRotation = %desiredRotation - $player.getRotation();
    $player.setRotation( $player.getRotation() + %newRotation / 10 );
}

Although it took me a while to figure out, that to enable onUpdate() calls one has to do the following:

$player.enableUpdateCallback();

Learning the hard way ;)
