Enable operation on non-crate directories, bug fixes, doc fixes

The major changes made in this commit are to how Carnet deals with
non-crate directories (now permitted instead of immediate failure).

Other notable bug fixes and features in this commit:

- Print help message when no argument is given.
- Only acknowledge the first command as such and treat what follows
  as normal arguments.
- First commit to contain Carnet signatures of itself.
