Refactor of asset factory to address mutation/face controller logic
Fixes issue where face controller extrusions applied to a rotated or scaled mesh would be applied incorrectly. Now we create the mesh at the origin, deform it as required (scale), apply face controllers and finally relocate it as required (position and rotation). A relative level of detail is cascade into the generation for shapes like cylinder, which generate fewer faces for small objects.
