futility: Let each command provide its own help
Instead of a separate help function for each command, let's just
require each command to handle a --help option. This will make it
easier to layer the commands (for example, "sign" could have
several subcommand variants, each with its own help).
I also compared the result of running "futility help CMD" before
and after this change. The help still shows up correctly.
