Webshop demo not working

[florian-rabis]

Hi,
I had to adjust the settings.py to get the webshop example running.
It seems the picocss middleware is missing. Additionally, a line further down was duplicated.

...

MIDDLEWARES = [
    'lona_picocss.middlewares.LonaPicocssMiddleware',
]

...


FRONTEND_TEMPLATE = lona_picocss.settings.FRONTEND_TEMPLATE                          # one removed

...

I also had to add the demo directory to the Python path to ensure the modules were found correctly. Unfortunately, running the Makefile on Windows didn't work for me, even after adjusting all the paths.

After that, I was able to start everything using lona run-server --project-root="webshop" --settings="settings.py".
