Re: reset position of the controller using supervisor_field_set

Hello,

The "stand me up" trick won't work with Webots 5.1.6 as it was not 
implemented in the roboka world.
However, I just ported it from the previous contest and integrated it 
into Webots 5.1.7 which I just released now. So, rush to download Webots 
5.1.7 and you will see in the source code of the Roboka0.java controller 
how to set the robot at any position in the maze (this is done when 
pressing the Esc key, but you can do it programmatically as well). Of 
course this feature will be disabled in the contest matches (real robots 
can't fly that way), but I believe it is very useful for developing 
robot controllers.

Moreover, as requested by several people, I added new sample roboka 
worlds called roboka0.wbt, roboka1.wbt, roboka2.wbt and roboka3.wbt 
which offer different maze configurations.

Cheers,

-Olivier
