3ds demo cart section updated

[wraggster]

Yet another demo cart section update. A new European 3DS Demo cart is out, "Puzzler Dragons Z + Puzzler Dragons Super Mario Bros Edition" and I've been fortunate enough to snatch a copy (buy one). Also updated with scan of the US "Style Savvy Trendsetters" demo.
