Pypi prep

Install with pip install . Run with dragon

Still todo:

• Install stuff from Src (Just remembered this now, but we can do it the same as the stuff in dragontools/shutils)
• Decide exactly what we want accessible to the user in $DRAGONDIR
  • e.g. should defaults.yml and rules.yml be there? One downside is that won't be managed by pip. Perhaps the best option would be to keep that stuff managed by pip and """read only""" and then allow users to create rules in their own rules.yml and then chainmap them
• Make sure all the env vars and directory aliases are resolving properly. As of now dragon test will fail because of that
• Other stuff I'm to tired to think of
• Rewrite wizard. It is currently hacky as all hell

Oh also I'd be happy to run back over the python code in dragongen and such and pep8-ify it. There is still some unused imports, broken formatting, incorrect type annotations, etc.
