New game-specific pages

I also made a change that was requested through meta-Pokebase, to keep images show or hidden. By default, when you go to the stat Pokedex (and now many other pages as well), the Pokemon icons are hidden. If you click the link near the top of the page, it will permanently turn on the icons across the various pages. It may slow the pages down slightly (if you are using an older browser) but so far I haven't had any problems while testing it.

Finally, another small change - on our various tables across the site, like the stat Pokedex, the header now scrolls with the page, so you can always see which column in which - useful!
