Buy RKS: Updated

I created a "How to buy Rosenkreuzstilette" page and linked it on the sidebar via the button on the right (labeled [buy:rks]). That page used to link directly to the DLSite page for Rosenkreuzstilette, but now, it links to a small directory with links to the individual games. It's just a small detail, but it should make things a little neater. Go click the button, and give it a look!
