Update notes

Support for Python 3.7 has been dropped. Python 3.8 or newer is now required:

If you are using the docker image, it will be automatically taken care of.
If you are installing NEMO using pip, you will need to update your version of python, as well as your start/stop services to point to gunicorn from python 3.8

New features

Added Safety as a new main menu item. Safety issues and Safety data sheets have been moved under this new section to provide a main Safety "hub" in NEMO.
Added Safety items:
- It is a customizable list of Safety bullet points, consisting of a name, a description and (optionally) a list of documents.
- Safety items can be grouped in Safety categories.
- PDF and Video documents (.mp4, .ogv, .webm, .3gp) can be opened directly in NEMO (popup)
- All other types of documents will take the users to the link/download the file.
- Users can search through Safety items name and descriptions.
In Customization -> Safety, the Safety menu item can be hidden, as well as the Safety suggestions and SDS. Safety categories can be organized as flat/collapsible items all in one page, or as separate side sub-menu items.

Added update of os packages when building NEMO docker images, to guarantee the latest security patches and updates are installed.
Allowing user office members to force a user out of a tool.

Fixed an issue on Chrome (Windows only) and Safari when clicking the back button after a spinner was shown would keep that spinner on indefinitely.
