Middleware v1.32

This week’s release includes a new feature and changes to the way some AEX-9 endpoints response is computed.

There is a new page for some channel details that can be accessed by /v2/channels/:channel_id.

On AEX-9 endpoints the changes were:
/v2/aex9/:contract_id/balances and /aex9/balances/:contract_id use event-based indexed balances;
/v2/aex9/:contract_id/balances/:account_id gets the balance from chain by calling the contract.

Since there is no longer a need to call AEX-9 contracts while indexing the balances, which now are event-based, a conflict on optimistic lock issue was also solved by removing the async database transaction.
