49281b24e5 Move Tick out of Event 
Every Entry is now a Tick and the entries contain events.

cc9f0788aa Batch events 
It's now a Tick that locks down event order. Before this change, the
event order would be locked down in the order the server sees it.

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.

9834c251d0 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.

d1b6206858 Monomorphisize Entry and Event 
Transaction turned out to be the only struct worth making generic.

b725fdb093 Sha256Hash -> Hash 
Because in Loom, there's just the one. Hopefully no worries that it
shares a name with std::Hash.

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.

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
