Removed some stuff related to the old reloading mechanism.

CombinedConfiguration used to support a flag for triggering reloads on child
configurations. If set, on each property access all child configurations are
queried to initiate a reload if necessary. Reloading is now handled in a
different way; therefore, this mechanism could be removed.

Don't call non-private, non-final methods from the constructor.
