Reference implementation does not change transaction

[andymckay]

When a transaction is completed zippy sends a call to webpay (imitating what a vendor would do). Solitude gets that and passes it back to zippy and then calls zamboni to let it know its complete. fxpay polls the marketplace waiting for confirmation so thats the end point that matters.

However the transaction in solitude is never actually updated to completed, which is annoying for stats and general code completeness / sense. It would be nice if it did that.
