eldritch horrors 95a9a4cece libstore: don't derive store classes from their configs
the very slight speedup in config setting access is not worth the
maintenance overhead of conflating concers like this. the virtual
inheritance scheme used for configs requires too much duplication
of base class constructor arguments to be worth doing. perhaps we
should get rid of all virtual inheritance of data-membered bases?
