The way we handle singletons in QML, QML insists on allocating the objects. This leads to a very idiosyncratic way of handling singletons: The global instance pointer is set in the constructor. Unify all these by implementing a "SillySingleton" template. All of the weird singleton-classes can derive from this template and don't have to bother with reimplementing the instance() function with all the safety-checks, etc. This serves firstly as documentation but also improves debugging as we will now see wanted and unwanted creation and destruction of these weird singletons.
