EntityStore backed by Preferences API.

A root node is created in the System preferences, whose name is the same as the Application name (default:"Application").

Each entity is stored under its identity name.

Property types are converted to native Preferences API types as much as possible. All others will be serialized to a string using JSON.

ManyAssociations are stored as multi-line strings (one identity per line), and Associations are stored as the identity of the referenced Entity.

The main use of the EntityStore is for storage of ConfigurationComposites for ServiceComposites.
