need a working payment request generator #5630

@gavinandresen Could you rework your generator under https://bitcoincore.org/~gavin/createpaymentrequest.php to allow zero amounts and also add some possibility to allow creating a valid authenticated testnet payment request?

I'm mostly using your site to test changes I make to our implementation, but can't get any valid authenticated request from it because of GUI: PaymentRequestPlus::getMerchant: Payment request: certificate chain empty.

I'd also like to be able to implement and test setting the (as per BIP70 optional) amount field to zero and query the user for an amount, which I can't because your page doesn't allow it :).

Thanks!
