Rather than reproducing the fee calculation in `apply`, we now require
that the transaction itself _say_ it wants a discount for being
challenged.  wellFormed insists that such a transaction avoid using
notes and such, and `apply` checks that such a transaction is actualy
challenged.

This means that heartbeats are more natural - even discounted ones can
appear in groups (though such a use is unlikely, I suppose).
