DomainEvent: Support type hierarchies

Why:
- It's useful to be able to listen to sets of compatible event types.

What:
- Make DomainEvents aware of a list of types they are compatible with.
- Make EventDispatchEngine dispatch to all compatible listeners,
  registered for any of the supported types.
- Move all page events to their own namespace
