Add more elements to the test_scene

Now cylinder and sphere have lights inside and the scene is enclosed in
another sphere.
The cylinder from inside is curious. The bases have very dark edges,
which looks obviously wrong, but it is direct consequence of only
tracing rays from object to lights. Proper ambient lighting would fix
this (but is outside of the scope of miniRT).
