Support readonly properties for references.

Browse Source 
The `@ReadOnlyProperty` annotation is now honoured for references to entities or collections of entities.

For tables mapped to such annotated references, no insert, delete or update statements will be created.
The user has to maintain that data through some other means.
These could be triggers or external process or `ON DELETE CASCADE` configuration in the database schema.

Closes #1249
