Chris Josten 1e80ceb697 Deserialized a list! Restructured project!
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.
