Directory permissions issue #41
Description
It seems the default permissions in the Docker container for the downloads directory at /home/wis2downloader/app/data/downloads aren't set correctly by default?
I login to the wis2downloader Docker container, as the wis2downloader user, but get a permission denied when trying to add a subscription:
`Subscription not added
Error: 500
<!doctype html>
Internal Server Error
Internal server error: [Errno 13] Permission denied: '/home/wis2downloader/app/data/downloads/.session-info.json'
`Permissions were set to 755 on the /home/wis2downloader/app/data/downloads directory. I changed it to 777 for the sake of testing and was then able to add a subscription successfully.
