Updating the Prim Ref page

[Willy Tschager]

I started copying the Curved primitives. I'm getting my hand wet on learning wiki formatting so I didn't check what's missing - for example -  in the ring section. I would leave that to you. So please check what sections of discs, chrds or rings are missing and report them with the correct row:

r=1 : 1-16rin1, 1-8ring1, 3-16rin1, 1-4ring1, 3-8ring1, 7-16rin1, 2-4ring1, 5-8ring1, 3-4ring1, 7-8ring1, 4-4ring1

Thanks,
