Improve persisted configuration handling

Browse Source 
When a persisted configuration file is read, the values in it are
considered to be more up-to-date than the ones in the main configuration
file. This allows all objects to be persisted in a more complete form
making it easier to change configuration values at runtime.

This change is intended to help make runtime alterations to services
possible.
