Description

This is a proposal for a configuration able to be reloaded automatically when
its source has changed. The implementation consists in :

• a PersistentConfiguration interface extending the Configuration interface and
  adding the load() and save() methods.
• a ReloadableConfiguration acting as a decorator around an existing
  PersistentConfiguration and intercepting the calls to the various getXXX methods
  of the Configuration interface to trigger a reloading if needed.
• a ReloadingStrategy interface deciding when the configuration should be
  reloaded.

An implemention of the ReloadingStrategy for file based configurations is
provided in the patch.
