Generator: Add validations for DomainObject attribute names reserved for persistence or auditing

[tjuerge]

If DomainObject attribute names which are reserved for persistence or auditing (e.g. id, key, version, uuid, createdDate, ...) are used in the DSL then Sculptor generates invalid code:

ValueObject InvalidAttributes {
    !immutable
    - @InvalidAttributes2 id
    long ^key
    Date uuid
    String version
    String createdDate
}

BasicType InvalidAttributes2 {
    String id
}

So we need a set of validations for attribute names which are reserved for certain domain object configurations.

Despite of being valid adding an attribute named "id" to a BasicType generates wrong code.
