Huge Info Update

I’ve just finished updating release dates, prices, and ISBN numbers for all the DC books. Comic store delivery dates now match the dates Penguin delivers to the book stores (as per the UCS website) so I’ve fixed most of those up now. As DC no longer has Diamond codes (obviously), I’ve linked all the DC entries to the prhinternational site for extra info beyond the basics.

I’ve also updated the entries for everything else but Marvel with the current dates from Previews as well as prices.
