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).

Remove the todo list in Main.kt, it just changes too fast to be worth keeping it up to date. TODOs in the code itself remain.

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).

Cash contract: Introduce a DepositPointer abstraction for easier grouping
...
In this current model, you cannot mix up money from different deposits: they must always be kept separate.

Cash contract: multi-issuer support
...
You can now take deposits from multiple different institutions and move/combine/split them appropriately. The issuers are kept separate, you cannot merge 3 different input states from 3 different institutions down to one, but you can merge/split within that specific issuer. Deposit refs are not currently being kept separate, but they should be also (this is coming next).
