v4.21.0

This release fixes the following bugs:

• If the heatmap changed because the project settings were adjusted, the settings screen did not close properly. That has now been fixed.
• If the brainstorm facilitator wants to close the page and clicks “cancel” in the confirm screen, the brainstorm now remains intact again.
• Nested filters remain selected when the user returns to the project screen from the OGM screen.
• A template with linked files can now be saved again
• If creating a file based on an Excel file does not go well, the load spinner now disappears again.

New features have also been added:

• In the dashboard, a 'neutral' sorting can now also be selected in the table. This makes sorting in the dashboard more intuitive
• The risk edit screen has now been tabbed, making it more similar to the project editing screen.
