The math was a bit busted, and QML needed to QQuick3DNode to be
registered.

Quaternion.lookAt(...)'s function signature changed a bit to accommodate
some default arguments.  The return of this function is the relative
transformation that needs to be made to get the correct lookat value, so
to use it you either need to use the default forward/up vectors to get
the global rotation, or the current forward/up vectors to get the
relative change.

Implement QQuick3DCamera::lookAt() using Euler angles to avoid
rolling the camera.

Applying a value of 35 created a very diffuse shadow with many artifacts
rather than simply bluring the edges a bit to create a softer edge to
shadows.  A value of 5 will provide significantly harder shadows, but
still with some softness (not pixel aliased, but will show polygon edges
for low-poly meshes). This is a more sensible default that will look
better in most scenes.

This is a behavior change, but since shadows generally didn't look
correct before, most "real" scenes manually adjust the shadowFactor
already.
