Flesh out timestamping logic and fix various serialisation related bugs that it exposes. Timestamps are optional, so update the CommercialPaper contract and tutorial to reflect that.

Contracts: make the Cash craftSpend/generate function update a mutable transaction instead of returning a unit test structure.
...
Tests: move TestUtils into the test package now the cash contract generate function works the right way.
Transactions: various refactorings to support partially signed transactions.

Major: Integrate serialisation everywhere, implement basic signing/sig checking code.
...
Currently the serialised forms and the form fed into the contract aren't quite joined up, because on disk/network a transaction is serialised with input references i.e. (txhash, output index) pairs, but the contract wants to see all input states in fully loaded form. To do that, we need some notion of a database of transactions.

Minor: make commands singletons when they contain no data and are purely type system markers.
...
This may not be really compatible with sandboxing, later on. But we can always change it back if not.

Platform: commands can now have multiple signatures per command (i.e. you only have one command of any type per transaction even if there are multiple authorisations).

Platform: fix the ability to summon cash in uncontrolled ways.
...
Introduce three ways to represent transactions: wire, ledger and for-verification.
TransactionForVerification contains the arguments formally passed to verify(). Making Contract.verify() take only a single object as the argument makes it easier to evolve the Contract binary interface without breaking backwards compatibility with existing contracts that are uploaded to the ledger. The Kotlin "with" construct can be used to bring the members into scope, thus acting syntactically like function arguments.
Make the contracts to be run depend on both input AND output states: this approach seems simpler than trying to have some notion of marking outputs that are checked. The TransactionForVerification class implements this simple logic (it's all moved into Transactions.kt).
