Full Changelog: v20.2.2...v20.2.3

Bug Fix release

In this release:

• Fix file previews in history
• Simplify History view
• Fix model download with links
• Fix FreeCAD prompting for file save when downloading model

Change file id, breaking change

The file ID is now deduced from FreeCAD.ActiveDocument.Uid. Before it was generated from an external library.

Consequences:

• Code is simpler
• No need to save object before uploading
• Files won't need extra UI save, which is a big win..
• But your files will be re-uploaded as new model if you do not re-create the database

It should now be stable on the long term.
