The log crate was starting to be the catch-all for all things related to entries, events, signatures, and hashes. This split shows us that: * Event depends only on signatures, not on hashes [directly] * All event testing was done via log testing (shame on me) * Accounting depends only on events
accountant crate shouldn't verify the log. Instead, it should only add valid entries and leave verification to network nodes.
Before this change, a client could spend funds before the accountant processed a previous spend. With this change in place, the accountant updates balances immediately, but that comes at an architectural cost. The accountant now verifies signatures on behalf of the historian, so that it can ensure logging will not fail.
Do all input validation first, then log (which can fail). If all goes swimmingly, process the transaction.
We don't do retries yet, so keep tx count to something that won't trigger any packet loss.
If a Transaction doesn't have an existing address, it's being used to create new funds.
Otherwise, the accountant will treat deposits of the same amount as duplicates.
It's now represented as a Transaction from an unknown party.
Without this, the accountant will reject transfers from different entities if they are for the same amount and to the same entity.

Instead of adding another event type for multisig transactions, moving towards a unified Transaction type that can represents deposits, withdraws (for side-chains), today's simple transactions, and multisig transactions.
