coin moves: record their attempted cheat (and our handling thereof)

Browse Source 
For cheats, we do a little bit of weird accounting. First we 'update'
our on-ledger balance to be the entirety of the channel's balance. Then,
as outputs get resolved, we record the fees and outputs as withdrawals
from this amount.

It's possible that they might successfully 'cheat', in which case we
record those as 'penalty' but debits (not credits).
