This also adds the constructor to the plugin class, as it should now be
called to register the qml types.
Dynamic linking mostly has its problem on Sailfish OS, as it creates
larger binaries and RPMs. Since this is the only application consuming
it, I see no benefit in using it.
I finally got deserializing lists working. Exposing them to QML was not
a trivial task either. Note that I didn't do it the clean way. Nested
lists are not supported. But it works!
Because I got so frustarted at one point trying to implement things the
right way, I restructured the project to seperate the Sailfish code from
the Qt code and created a new, empty desktop project. The Qt code has
been transformed into a happy little library, to which the Sailfish OS
application links.
Note that QMake doesn't seem to strip the library for some reason.
