* QMC Raytracing

This introduces QMC sampling for use in glossy reflections/refractions, soft raytraced shadows, and ambient occlusion.

This work includes many new features and speed-ups, so check out the nice docs here:

Many thanks to Brecht van Lommel for some initial code snippets and for reviewing the patch, and especially to Alfredo de Greef who gave me a lot of guidance and help along the way!
