Receive: tx scanner for payments matching setup

Payments matching the currently setup payment id and optional amount
are detected, allowing a merchant to generate a new payment id, enter
the expected amount, let a client scan the QR code, and wait till
the payment shows up as either in the txpool, or with N confirmations.
