Move party classes into identity package

Move AbstractParty, AnonymousParty and Party into a new net.corda.core.identity package,
as they're not really cryptography tools, and in preparation for further code coming in
for identity.

Optimize imports on many files to clean up the resulting refactor.

- * The [Party] class represents an entity on the network, which is typically identified by a legal [name] and public key
- * that it can sign transactions under. As parties may use multiple keys for signing and, for example, have offline backup
- * keys, the "public key" of a party can be represented by a composite construct – a [CompositeKey], which combines multiple
- * cryptographic public key primitives into a tree structure.
- *
- * For example: Alice has two key pairs (pub1/priv1 and pub2/priv2), and wants to be able to sign transactions with either of them.
- * Her advertised [Party] then has a legal X.500 [name] "CN=Alice Corp,O=Alice Corp,L=London,C=UK" and an [owningKey]
- * "pub1 or pub2".
- *
- * [Party] is also used for service identities. E.g. Alice may also be running an interest rate oracle on her Corda node,
- * which requires a separate signing key (and an identifying name). Services can also be distributed – run by a coordinated
- * cluster of Corda nodes. A [Party] representing a distributed service will use a composite key containing all
- * individual cluster nodes' public keys. Each of the nodes in the cluster will advertise the same group [Party].
- *
- * Note that equality is based solely on the owning key.

+         * There is a new ``AbstractParty`` superclass to ``Party``, which contains just the public key. A new class
+           ``AnonymousParty`` has been added, which is intended to be used in place of ``Party`` or ``PublicKey`` in contract

+           issuer of a ``Cash`` state.
+         * Names of parties are now stored as a ``X500Name`` rather than a ``String``, to correctly enforce basic structure of the
+           name. As a result all node legal names must now be structured as X.500 distinguished names.
+
 * The ``InitiatingFlow`` annotation also has an integer ``version`` property which assigns the initiating flow a version
   number, defaulting to 1 if it's specified. The flow version is included in the flow session request and the counterparty
   will only respond and start their own flow if the version number matches to the one they've registered with. At some
