When I was praticing in editmod, I found that some of the things I was making fit perfectly in the map spiralz.

I added two different spiral stairs, two really different Da Vinci's stairs -double helix stairs-, inside a tower or not, squared or rounded. The big difference with de DV's stairs is that one is wide enought to let a player jump without collide with the "ceiling".

I named the map spiralz2, but I didn't change anything of the original stuff. So you can replace spiralz by this one if you wish.

edit: packaging fixed (I hope).
