UPDATE

0.8->0.81
* Changed default colors and ground texture
  - in order to get the old look and feel use
  in ThisSim() constructor:
   setGroundTexture("Images/greenground.rgb");
   addPaletteFile("colors/DefaultColors-0_8.gpl");
   addColorAliasFile("colors/DefaultColorSchema-0_8.txt");
  for UrbanColorScheme:
   addColorAliasFile("colors/UrbanColorSchema_old.txt");



0.7->0.8

* All OdeRobots subclasses have to be changed:
   getSensors() -> getSensorsIntern()
   getMotors() -> getMotorsIntern()
   getSensorNumber() -> getSensorNumberIntern()
   getMotorNumber() -> getMotorNumberIntern()
   place() -> placeIntern
   In doInternalStuff() call OdeRobots::doInternalStuff()
   In update() call OdeRobots::update() and remove the update of all
    primitive and joints
   Typically you can remove the update and doInternalStuff functions and just the primitives you update
    etc to the object list


* AddSensorToRobotAdapter is removed, use addSensor directly at the OdeRobot

* all Sensors: std::list<sensor> get() was renamed to getList()

* IRSensors: they are generic Sensors now, actually PhysicalSensors.
  Use setInitData(). Use sense() (before step) and not reset() (done automatically if attached)
  Can be generically attached to a robot, just use addSensor(..)).
  so: init(..) -> setInitData(...). The init() function is called when attached automatically.
