Rename Genesis to Mint
...
Genesis is a story of creation. We should only use that term to
for the event log that bootstraps the system.

Boot genesis block helper
...
Before this change, if you wanted to use a new Transaction
feature in the genesis block, you'd need to extend its
Creator object and associated methods. With yesterday's
addtions to Transcation, it's now so easy to work with
Transactions directly that we can get rid of the middleman.
Also added a KeyPair type alias, so that ring could be easily swapped
out with a competing library, if needed.

Transactions now require a hash of the last entry they've seen
...
This ensures the transaction cannot be processed on a chain
that forked before that ID. It will also provide a basis for
expiration constraints. A client may want their transaction
to expire, and the generators may want to reject transactions
that have been floating in the ether for years.

Boot wait_on_signature() from accountant

Instead, there should be a way to query for a page of log data,
and checking whether it has a signature should be done client-side.

Logger now only speaks when spoken to
...
Before this change, the logger's send channel could quickly be
flooded with Tick events. Those events should only be passed to
a writer.
Also, the log_event() function no longer sends entries. That
functionality moved to the new process_events() function. This
will allow us to initialize the with the genesis block without
flooding the send channel with events the historian won't read.

More defense against a double-spend attack
...
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.

Move Event into its own crate
...
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
