@EqualsAndHashCode should allow for calling superclass if superclass is not Object

[lucasmo]

We have a lot of JAXB-generated classes from externally supplied schema. We typically want to add equals and hashcode methods to each of these classes. There are packages to automatically add annotations to JAXB-generated classes, but it's not simple to set callSuper to true if and only if the class has no extensions.

Would it be possible for callSuper to have an 'automatic' mode, which calls the superclass method iif that class is not Object?

Now we have lombok.config it might be possible without breaking backwards compatibility.
