Plumb attachments through to the contract verify functions (no contract uses them yet).
...
The right way to do this is probably to put the contracts onto the classpath before execution of the contract. However, this interacts closely with the sandboxing work, which isn't yet started, so for now this will do.

Integrate a simple progress tracking system into the protocol framework.
...
The progress tracker API lets you model a tree of steps, along the same structure as protocols and subprotocols. Each step has an (optionally changing) label, and thus progress trackers can be arranged in a tree. Updates to the progress at each level flow up the tree via an RxJava observable (I guess we will use this more in future).
A simple console renderer is provided that uses ANSI escapes and Emoji to show animated progress through a protocol.
The trader demo is enhanced to use this framework, when run outside of Gradle.

Major: Separate out the dep resolution protocol into a couple of sub protocols and use on both sides of the trade.
...
* Dependency resolution/checking is now working on both sides of the two party trading protocol.
* The commercial paper contract was changed to check timestamping authority identities by name instead of key.
* The trader demo has been rewritten to use the protocol framework, which simplifies the code.

Refactor the 2-party trading protocol
...
- Fix a security bug/TODO by having seller send back the signatures rather than a full blown transaction (which would allow a malicious seller to try and confuse the buyer by sending back a completely different TX to the one he proposed)
- Introduce an UntrustworthyData<T> wrapper as an (inefficient) form of taint tracking, to make it harder to forget that data has come from an untrustworthy source and may be malicious.
- Split the giant {Buyer, Seller}.call() methods into a set of smaller methods that make it easier to unit test various kinds of failure/skip bits in tests that aren't needed.
