contained only if the signature on it is valid.

c8865c1b40 Remove deregisterIdentity() 
Remove the ability to remove registered identities. Once registered, identities are part
of a permanent record (for example you would want to ensure parties to contracts cannot
"disappear" by removing themselves from the identity service).

b4513e8bec Add InMemoryIdentityService 
Move FixedIdentityService to MockIdentityService under testing as it's specialised for use in tests.
Add a new InMemoryIdentityService replacing the fixed identity service in AbstractNode.

fcc36c472a Improve the contracts API and Cash contract a bit, and beef up the unit tests. 
Better usage of generics in groupStates so the group exposes the grouping key that was used, this avoids constructs like `val issuer = outputs[0].deposit.party` which is a bit ugly.

2de44a516f Switch Kryo serialisation to always include the class name, and avoid overhead from writing out SerializedBytes wrapper data. 
This simplifies the serialisation code, reduces the use of inline functions, and ensures that running SerializedBytes<SuperClass>.deserialise() will correctly return SubClass if that's what it contained, efficiently.

2754546942 Don't report errors when dependency version conflicts are found, as Gradle's default behaviour of picking the newest version is normally the right one and in practice what we've been doing anyway. 
Remove RxKotlin. It doesn't add enough value over just using the RxJava API directly.

6cb86ab840 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.

c3f86f6557 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.

Mike Hearn
cd28733360 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.

df4d926bca First pass at implementing dependency resolution and checking in the two-party trade protocol. 
This commit is incomplete: only the seller side currently checks. The code will be refactored out into subprotocols in further commits.

Note that timeouts are currently unhandled.
