Create proper Quick extended classes in scene loaders

This allows exploring the loaded subtrees from QML/Javascript code. The
C++ classes are not suitable for this as they lack properties that involve
QML specifics.

The assimp (QML) example is updated to show how to do this (with the help
of some C++ code). Say hello to the pulsating torus and the rotating monkey!
