Re-add the block of text explaining the feature.

When the automatic storage manager is off (or has never been run), we display a block of text that explains what it does. In order to make this testable, I've implemented the feature in a PreferenceController and upgraded the existing AutomaticStorageManagerSettings class to be closer to the newer Settings IA.
