Title: [Qt] ensure payment request network matches client network

- introduce a new function PaymentServer::validatePaymentRequest(), which
replaces checks in SendCoinsDialog::handlePaymentRequest() that belong
to PaymentServer (normal URIs are special cased, as only an isValid
check is done on BTC addresses)
- prevents the client to handle payment requests that do not match the
clients network and shows an error instead (mainly a problem with
drag&drop payment requests onto the client window)
