Add observable for transactions being stored, so the UI can show transactions as they're received, rather than being
limited to the summarised version available from the wallet service.
- Fix thread safety issues in ArtemisMessagingClient. The Artemis API isn't thread safe, but that isn't well documented and it will happily invoke callbacks in parallel.
- Add discussion of how we tackle threading currently in the codebase and make a few other improvements.
- Add a shutdown hook so we stop properly when the user presses ctrl-c

Review feedback. Main change is lazy wallet iteration.
Rebased and incorporated config changes.
Use standardised config loading. Make wallet cash test use persistent wallet.
Added test to ensure wallet retains state in database across instance creation.
Tidy up whitespace and fix bug in test.
Changes include:
- LedgerTransaction is now much more central: it represents a fully resolved and looked-up tx, with the inputs available.
- TransactionGroup and TransactionForVerification are gone. There is a temporary TransactionForContract class for backwards
compatibility but it will also be gone soon.
- ResolveTransactionsProtocol is simplified, and now commits a tx to the database as soon as it's determined to be valid.
- ServiceHub is now passed in more consistently to verification code, so we can use more services in future more easily e.g. a sandboxing service.
- A variety of APIs have been tweaked or documented better.
This change reduces the testing confusion that can occur when cash is issued by one of the parties in a transaction rather than e.g. a neutral third party like a central bank.
Break down what is referred to as "topic" of a message into its component parts. This splits the
general topic from the session ID, so it's clear where a session ID is provided, and whether any
given topic string includes a session ID or not.
Move FiberRequest out to a top level class, both because it is expanding as functionality is added,
and to enable alternative state machine implementations to share it.
Unhandled messages in the in memory messaging network can disrupt runNetwork(), as they
result in getNextQueue() returning null, irrespective of whether there is further work
which could be done. This modifies the flow to loop through the remaining transfers on
the queue before giving up, rather than stopping after the first.
- Move code out of ambiguously named TestUtils files (there were three). Sometimes it's simpler to just put these things into the contract source files directly.
- Remove JavaTestHelpers objects (there were three), in favour of just giving the top level kotlin file class better names.
- Misc other small tweaks and cleanups.
As the timestamping authority is now always the notary service, contracts should
no longer be using name-based lookup of the timestamping authority (as this will
generally be wrong). This introduces a new "timestamp" property on a transaction,
and updates most contracts to refer to it.
In some cases (IRS, CommercialPaper) there are transactions with no input states
to derive notary from, that use timestamps. In these cases a notary is specified
in the command.
