Important Updates:

- FunctionCore:
  - Output() returns largest no of bytes written to linked input
- SelectableCore:
  - Auto-manage:
    - Add AutoManage param -> Persistent
    - Will automatic open port if written to when Auto-Manage enabled
    - Will keep port open (re-open if closed) if Persistent = true
  - DNS resolve:
    - Set AddressFailed if port could not open/bind
    - Only use next resolved address if current address failed
