Release Notes: A new module called ujo-wicket to provide a model for the Wicket framework from Ujo objects. A new class KeyFactory for an alternative way to create new ujo keys. The new interface WeakKey without the generic domain type parameter is finished; it is the simplified Key. A new class KeyRing intended to create a serializable and immutable Key collection. The class SpringKeyFactory is implemented to create special Keys; see the new class ApplicationContextAdapter. The class TypeService is replaced with a new interface ITypeService for better type-safe specification by Java generics.
