Double tessellation numbers for these 3 functions in your code to get same results as in Irrlicht 1.8
I noticed in last commit those all tessellated semi-circles instead of circles. I just documented it there, but it's annoying as that bug doesn't allow odd numbered tessellation. So for example one couldn't create a triangle pyramid.
I considered adding another parameter to describe what this number means, but... just too ugly. And it was always documented otherwise, so this could be considered a bug. Sorry if this changes the look of existing apps.
Also cleaned up code in CGeometryCreator::createCylinderMesh. No idea what the idea behind old code was. Aside from creating twice the tessellation numbers.
