Interactive configuration (#1517)

* Update scripts/configure_invokeai.py

prevent crash if output exists

Co-authored-by: psychedelicious <4822129+psychedelicious@users.noreply.github.com>

* implement changes requested by reviews

* default to correct root and output directory on Windows systems

- Previously the script was relying on the readline buffer editing
  feature to set up the correct default. But this feature doesn't
  exist on windows.

- This commit detects when user typed return with an empty directory
  value and replaces with the default directory.

* improved readability of directory choices

* Update scripts/configure_invokeai.py

* better error reporting at startup

- If user tries to run the script outside of the repo or runtime directory,
  a more informative message will appear explaining the problem.
