2017 Grand Prix

I added a new cycle (C28 using my name and numbering conventions) to my index page on the World Chess Championship. The first event in the new cycle will be the 2017 Grand Prix, for which I created a new page.

Two small evolutions are worth noting. Excluding the zonal stage, C28 will be the first cycle in 12 years that doesn't overlap the previous cycle. The cycle's Grand Prix will be the first to fall within a single calendar year.
