	Applications can use the index to detect replays of the same message.

2016-09-13	Use the ed22519 public key as the group session id.	Mark Haines
	Some clients expect the session id to be globally unique, so allowing the end devices to pick the session id will cause problems. Include the current ratchet index with the initial keys, this decreases the risk that the client will supply the wrong index causing problems. Sign the initial keys with the ratchet ed25519 key, this reduces the risk of a client claiming a session that they didn't create.
2016-09-06	Sign megolm messages	Richard van der Hoff
	Add ed25519 keys to the inbound and outbound sessions, and use them to sign and verify megolm messages. We just stuff the ed25519 public key in alongside the megolm session key (and add a version byte), to save adding more boilerplate to the JS/python/etc layers.
