Ability to create new identities (named public-private key pairs)

[DivineOmega]

Currently there is only one main identify (public-private key pair) created. It would be useful for applications to be able to create their own identities (and thus DM addresses) and name them appropriately.

This would require:

• A new identity database table containing:
  • id
  • name - the identities name used for initial creation and retrieval
  • privatekey_id - key linking to privatekey table
  • publickey_id - key linking to publickey table
• Three new local API commands:
  • Generate a new identity specifying its name
  • Retrieval of the DM address of a specific identity (by name)
  • Ability to send a DM message using a specific identity
• Modification of decryption code to attempt decryption using all private keys
• Modification of encryption code to allow specification of an identity (and thus public key) to use for encryption

Or alternatively, and more simply, applications could simply prefix the subject of their messages with a string that uniquely identifies the application.

Perhaps not required now, as each program can now have their own instance of Decent Messaging via the portable mode implemented in #14.
