Remove `renderSVGIcon()` and `renderSVGIconWidth()`, as QPixmaps can be
loaded directly from SVG, and support scaling.

In order to be able to correctly size the chart type popup, we'll need
access to the total count or rows as a property that signals changes to
QML.
The hack to use rowCount() as the READ function requires that rowCount()
can be called without argument, therefore the addition of a default
parent.

For QML, the roles have to be associated dynamically with
name. Moreover, the model has to be registered as a QML
type to make it accessible from QML.

Qt's comboboxes are controlled by models, there's no way around
that. To customize the chart-selection widget this must therefore
be abstracted into a model. On the upside, this hopefully can
be used for desktop and mobile.
The model provides icons and paints a warning-symbol on it
if the statistics core code deems the chart to be not recommended.
Notably, when plotting a categorical bar chart against a
numerical value (in such a case histograms are preferred).
Includes a fix for a silly oversight in CMakelist.txt: add the
statstranslations.h header.
