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.

Following KDE Pholio M116, switch to using a radio button; instead
of 4 individually toggle-able settings, use a "level" indicator
to select none, install, machine, user .. each of which implies
the previous levels. Each level is individually enable-able from
the distro side.
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.

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.

Each kind of tracking has an associated webpage / URL describing
the policy for that tracking. The Calamares User Guide has some
generic information. When the user clicks on the Help (?) button
in a tracking-option block, go to that URL.
- Enable translations, substitute ShortProductName into string,
- Simplify code for enabling tracking option blocks,
- Set checkboxes based on configuration,
- Read checkboxes when leaving page,
- Don't stretch the tracking option blocks.
- add icons for graphical display of actions
- extend description of tracking options
- add debug logging
- enable next button
- show/hide tracking options based on configuration
- m_groups is only set to a non-nullptr value when data is received
and fully processed,
- avoid nullptr dereference when paging *back* from a netinstall
page that hasn't loaded groups data.
FIXES#859
- Document netinstall.conf a little,
- Add setting *required* which influences whether next is enabled or not
in case of missing or corrupt data,
- Enable *next* button only once some (any!) data is received.
This can be used to disallow stepping past the netinstall step when
there is no data (e.g. internet has failed between the welcome page
and the netinstall page).
- Warn here since it may not be what the Distributor want.
Having wrong groups may result in broken permissions for
created user.
- explain what defaultGroups is for in users.conf
