Bug 206093

Continuation of JG04 from bug #183794. In practice there are some actions which simply cannot be registered using lazy factories, and convincing the action processor to use a traditional eager registration for them is cumbersome and error-prone: you have to know to implement a special interface like ContextAwareAction and then somehow implement it without changing semantics.

While my original preference was for a separate annotation for such actions, an attribute lazy=false (with default being true) in @ActionRegistration would suffice. When lazy=false, the processor would create a traditional registration rather than using an Actions factory method.

Attempting to use lazy=false would result in an error when only a factory method could make sense, e.g. the class implements only ActionListener and not Action, or it has a context constructor.

For compatibility, existing (implicitly lazy=true) registrations on classes which implement ContextAwareAction, Presenter.*, or DynamicMenuContent would continue to processed as eager, but a warning should be issued. (To use a lazy factory, specify lazy=true explicitly; the processor can use AnnotationMirror.getElementValues to distinguish this case. Of course such registrations will not generally work as intended, but there might be reasons to do it.)
