- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
- Instead of loading all in the constructor, provide a public
setupModelData().
- This allows creating the model and setting it for UI, before
the load completes.
- Check groups
- Check whole treemodels recursively (this is not in PackageTreeItem,
because that explicitly ignores the tree structure).
- Also a stub of checking example files (from the src dir)
- Just some simple tests for the Items
- Test creation of package group from variant
- This needs Qt5::Gui to link because QStandardItem is a GUI class,
although we can run the tests without a GUI.
