CURA-4451
- Add upgrade script for 3.0. to 3.1
- Upgrade old stack files so they will use "empty_quality" as the
"Not Supported" quality profile.
- Increase SettingVersion to 4
These are now upgraded to version 3, meaning that they will have to increase their version numbers and remove any start_layers_at_same_position settings they define. None of these profiles define any start_layers_at_same_position so it's just the version number then.
Contributes to issue CURA-3479.
The Ultimaker 3 is now released, so we can make this data public. These are the Ultimaker 3 definition files (with their physical properties as Cura requires them, such as build volume) as well as its extruders, print cores, quality profiles and build plate mesh. And also for the Ultimaker 3 Extended. Modifications to the material profiles will be published in the fdm_materials repository.
Contributes to issue CURA-2737.
