Fixed Issue #11, "Price fetcher is broken"

Price scraping now works. 

Also note that the "price" command doesn't require a full card name. For example, typing `price boob` will bring up the price for "Booby Trap", and `price lim-dul` will bring up the price for the first matching card, which I believe is "Legions of Lim-Dul". This may have been the same behavior as the previous price scraping, but I'm not sure. I figured I'd mention it.
