PersistencePlugin does not generate Cascade

This is one of those 'we could do it a different way, but it would make the generated code cleaner if...' requests

At present the PersistencePlugin generates:

@OneToOne
private Profile profile;

public Profile getProfile()

{ return this.profile; }

public void setProfile(final Profile profile) { this.profile = profile; }

I would instead like it to generate:

@OneToOne(cascade = CascadeType.ALL)
private Profile profile;

public Profile getProfile() { return this.profile; }

public void setProfile(final Profile profile)

{ this.profile = profile; }
