--------------------------------

       Resolution: Fixed
    Fix Version/s:     (was: 3.1M1)
                   3.1M2

Checked in a basic implementation. One fuzzy area is inheritance in listener classes.

> Add annotations for lifecycle events:
> @PrePersist, @PostPersist, etc. (all the standard ones, total of 8 annotations)
> Each annotated method can process events for preset collection of entity classes and/or a set of unknown entity classes tagged with a custom annotation. In the later case a listener is cleanly decoupled from specific entities (this feature is mixin-inspired). E.g:
> @Target(METHOD) @Retention(RUNTIME)
> @PrePersist {
>    Class<? extends Persistent>[] entityTypes();
>    Class<? extends Annotation>[] entityAnnotations();
> }
> LifecycleCallbackRegistry API:
> /**
>  * This form of listener registration is very simple and type-safe compared to other forms available in 3.0 LifecycleCallbackRegistry.
>  */
> public void addListener(Object annotatedListener);
