Pychess. Missing description

I made one slight tweak to the description, changing "we use" to "it uses". I suspect this description was copied from a PyChess website, and it would be better for it to be rewritten from the point of view of a user telling people here about PyChess.

Instead of just listing games that Pychess supports in the description, how about going to our pages for these games (at least those we have), and adding the Pychess tag to them?
