Shawn O. Pearce	8a9844b2af	Redo event listeners to be more generic Replace the old crude event listener system with a much more generic implementation, patterned after the event dispatch techniques used in Google Web Toolkit 1.5 and later. Each event delivers to an interface that defines a single method, and the event itself is what performs the delivery in a type-safe way through its own dispatch method. Listeners are registered in a generic listener list, indexed by the interface they implement and wish to receive an event for. Delivery of events is performed by looping through all listeners implementing the event's corresponding listener interface, and using the event's own dispatch method to deliver the event. This is the classical "double dispatch" pattern for event delivery. Listeners can be unregistered by invoking remove() on their registration handle. This change therefore requires application code to track the handle if it wishes to remove the listener at a later point in time. Event delivery is now exposed as a generic public method on the Repository class, making it easier for any type of message to be sent out to any type of listener that has registered, without needing to pre-arrange for type-safe fireFoo() methods. New event types can be added in the future simply by defining a new RepositoryEvent subclass and a corresponding RepositoryListener interface that it dispatches to. By always adding new events through a new interface, we never need to worry about defining an Adapter to provide default no-op implementations of new event methods.

Redo event listeners to be more generic

Replace the old crude event listener system with a much more generic
implementation, patterned after the event dispatch techniques used
in Google Web Toolkit 1.5 and later.

Each event delivers to an interface that defines a single method,
and the event itself is what performs the delivery in a type-safe
way through its own dispatch method.

Listeners are registered in a generic listener list, indexed by
the interface they implement and wish to receive an event for.
Delivery of events is performed by looping through all listeners
implementing the event's corresponding listener interface, and using
the event's own dispatch method to deliver the event.  This is the
classical "double dispatch" pattern for event delivery.

Listeners can be unregistered by invoking remove() on their
registration handle.  This change therefore requires application
code to track the handle if it wishes to remove the listener at a
later point in time.

Event delivery is now exposed as a generic public method on the
Repository class, making it easier for any type of message to
be sent out to any type of listener that has registered, without
needing to pre-arrange for type-safe fireFoo() methods.

New event types can be added in the future simply by defining a
new RepositoryEvent subclass and a corresponding RepositoryListener
interface that it dispatches to.  By always adding new events through
a new interface, we never need to worry about defining an Adapter
to provide default no-op implementations of new event methods.
