- 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.
- Groups inherit slightly differently: if a subgroup **explicitly**
configures criticalness, use that. It would be weird, but possibly,
to have a non-critical subgroup of a critical group.
- An unselected group with (some) selected subgroups was not
displayed as (semi)checked -- it was unchecked, because
its checked-ness was not updated based on the children.
- This doesn't compile right now.
- The nested class ItemData doesn't do anything useful or
meaningful that having model items with the right data wouldn't.
Root is always selected, can't be unselected, and has its own explicit
constructor and name. This resolves issue reported where unchecking
all *visible* groups caused the root to be unchecked, after which
hidden-but-still-selected subgroups were not installed.

If a subgroup is hidden, then it should be considered
selected if its parent is selected or partially-selected.
If the parent group is totally unselected, then the hidden
subgroup shouldn't be installed either. This allows putting
required-packages into a group, without cluttering the
interface.
FIXES#864
While walking up the tree, only switch the selectedness states
of parents with children. This avoids the case where a parent
has a first subgroup that is hidden -- in which case the
parent ends up with no children, and is unselected even though
it is marked as selected in the config file.
