Rewrote the argparsing functionality to enable autocompletion via the "kislyuk/argcomplete" package.

This essentially means:
- `argparsing.py` does a minimal amount of work to initialize the arg parser.
   Then it attempts dynamic completion.
- `argvalidation.py` processes the raw arguments parsed in
  `argparsing.py`, validates them, issues warnings (if required), and
  splits them into logical groupings
- Commands in `gcli.py` have been moved to `cmd.py`
- `main.py` provides an initial control path to call these functions in
  succession
