commands: Added a Format function to Command, for creating human-readable output based on a Response

commands: Silently skip unrecognized options, it should be up to the transport to decide if they cause an error

- distinguish log.Error and log.Errorf functions
- Initialize structs with field names
- A bit of unreachable code (defers)

commands: Removed Command#Register and exported Subcommands so subcommands can be defined statically
