Add list-strat and subproc-exe

Added

• Added the --{enable|disable}-error-format options to
  resolve-location and query-repo.

• Added the --package-system subproc option, together with its
  --subproc-exe and --subproc-output-format options.

• Added the --json-config global option allowing users
  to use JSON config files

• Added the --list-strat option to resolve-locations, allowing users to have their dependencies listed in a sane order.

Fixed

• JSON/EDN output for query-repo erroneously listed the subcommand as
  resolve-locations. Fixed.
