Ultra classic keyboard input handler

Oh yes, the ultra classic input handler for keyboard is up and ready - 4 directions, constant step distances in the cubic space! Also the J3DCore is now rendering dynamic range of the total area, called RenderedArea. So now I can walk around the random generated labyrinth. Nice, now I will make some smooth tuning on it, maybe get some better 3D wall model and then to begin other parts of the game. So some kind of iterative development to be done to have a simple but playable version soon. (You can check the sources in the new and active sourceforge project: link.)
