Andrea Maria Piana 7650f3003e Fix some issues with pinned messages
There were a couple of issues on how we handle pinned messages:

1) Clock of the message was only checked when saving, meaning that the
   client would receive potentially updates that were not to be
   processed.
2) We relied on the client to generate a notification for a pinned
   message by sending a normal message through the wire. This PR changes
   the behavior so that the notification is generated locally, either on
   response to a network event or client event.
3) When deleting a message, we pull all the replies/pinned notifications
   and send them over to the client so they know that those messages
   needs updating.

Hash ratchet encryption

encryptor.GenerateHashRatchetKey() generates a hash ratchet key and stores it in in the DB. There, 2 new tables are created: hash_ratchet_encryption and hash_ratchet_encryption_cache. Each hash ratchet key is uniquely identified by the (groupId, keyId) pair, where keyId is derived from a clock value.

protocol.BuildHashRatchetKeyExchangeMessage builds an 1-on-1 message containing the hash ratchet key, given it's ID.

protocol.BuildHashRatchetMessage builds a hash ratchet message with arbitrary payload, given groupId. It will use the latest hash ratchet key available. encryptor.encryptWithHR encrypts the payload using Hash Ratchet algorithms. Intermediate hashes are stored in hash_ratchet_encryption_cache table.

protocol.HandleMessage uses encryptor.decryptWithHR fn for decryption.
