Andrea Maria Piana 6acb34bab7 Allow setting up wallet with new config
This commit does a few things:

1) Extend create/import account endpoint to get wallet config, some of
   which has been moved to the backend
2) Set up a loop for retrieving balances every 10 minutes, caching the
   balances
3) Return information about which checks are not passing when trying to
   join a token gated community
4) Add tests to the token gated communities
5) Fixes an issue with addresses not matching when checking for
   permissions

The move to the wallet as a background task is not yet complete, I need
to publish a signal, and most likely I will disable it before merging
for now, as it's currently not used by desktop/mobile, but the PR was
  getting to big

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.
