0bec360a31 Revert TCP sync of ledger 
The feature was too rushed. We technically don't need it until we
implement consensus. It'll come back another day (with many more tests!)

98c0a2af87 tx confirmed/sec ---> tx processed/sec 
Before this patch, we were waiting until the full log was
sent back across the wire, parsed, and interpreted. That was giving
us a metric of "transactions confirmed per second" instead of
"transactions processed per second". Instead, we'll just send one
tiny packet back with the balance. As soon as the balance is what
we expect it to be, we end the benchmark.

5dd567deef 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.

48c28c2267 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.

d8c50b150c Move key generation and signing from transaction benchmark 
Key generation, signing and verification are not the performance
bottleneck. Something is probably wrong here.

32d677787b Reduce transactions sent by demo 
We don't do retries yet, so keep tx count to something that won't
trigger any packet loss.

1b77e8a69a 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
