The `init` function does not auto-execute anymore. It is instead added as a public member for `DaemonInterface` and called by `Pool.SetupDaemonInterface`.
Refactored, a bit, the emit log event introducing a key for every log message Current keys are:
- 'client': for all the client related events
- 'submitblock': dedicated only to events about the block submission!
- 'system': all log events about the stratum pool
