Revamp/document custom-extension example

This is a very useful example which was unfortunately
undocumented.

It also needed some clean-up in the code, and as part of
writing the documentation, it became clear that it would be
an easier demonstration to follow if the QML client was
more similar to the C++ client, so that they were simply two
implementations of the same spec.
