Some Refinements

I fixed some issues with the graphics and added some screenshots. Also I decided against including all the legacy versions of the game. It is supposed to be a living game, so older versions don't need to be frozen in time. I was thinking about ordering physical cards to test the game in meat-space, but since I don't have any players to play with *physically* I might as well save the money and hope for international player feedback!

Please poke me, if you find anything that needs a fix.
