In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
module builds, installs and runs, connections are not working yet.
UserQmlViewstep.cpp/h are from PR https://github.com/calamares/calamares/pull/1356
sections are commented out to make the module build, but help is needed to get those 2 files corrected.
config names used in usersq.qml are guessed from users/Config.cpp
debug window shows correct entries in GS, and under the module tab, usersq.conf is read
as should too. Running shows most config used in users.qml are not registered/wrong,
many entries like: qrc:/usersq.qml:228:13: Unable to assign [undefined] to bool
It is understood not all needed from the users module has moved to Config.cpp yet,
but doing the PR now, since it runs, doesn't crash cala and help is needed to further implement.
