Berthold Stoeger 0d011231e6 desktop: unglobalize ComboBox-models
The combo-boxes (cylinder type, weightsystem, etc.) were controlled
by global models. Keeping these models up-to-date was very combersome
and buggy.

Create a new model everytime a combobox is opened. Ultimately it
might even be better to create a copy of the strings and switch
to simple QStringListModel. Set data in the core directly and
don't do this via the models.

The result is much simpler and easier to handle.
