Class: Dsadmin::SingletonConfigManager

Singleton variant of BaseConfigManager.

Designed so that there is always only one instance of anything derived from this. To make that work, children have to provide:

A class method setup() to, well, set up a proper instance. This should call SingletonConfigManager.instance= at the end.
A private new class method (so that setup() is the only way of initializing an instance)
A class method instance as frontend for SingletonConfigManager.instance
