Stop nesting ObservedPtr inside Observable.
Now, only the ObservedPtr<> is templated, and a templated
Observable isn't required. Templated Observable<> lead to
templated Obeservable<>::ObserverIface, which made usage of
ObservedPtr<> to subclasses awkward, since the ObserverIfaces
weren't subclasses of each other even if the dependent types
were.
The majority of the change is to fix syntax now that
we no longer have a typename in the classes derived from
Observable.
- Rename Observable::Observer to ObserverIface for clarity.
