Infinite Stairs Castle

_Update_:

* I realized lots of .scad Downloads. I also realized that my uploaded code is not complete and therefore useless, because I modularized it and did not upload all my included models. __Now, the uploaded code is complete, with all included modules.__
* I also played around with the algorithm that produces the colours of the stairs. I now use RGB Colors with [sin(x),sin(x),sin(x)], just to be sure that all the values are between 0 and 1. And now, it is way more colorful :-)
