Sandbox3D v.0.0.0.4 -- Updated for Sept 05 CTP

I've updated Sandbox3D, an application that allows you to place primitives in a WPF 3D space and manipulate their transforms, including drawing video on them.  It also shows off some databinding.  No new features for this release, just the port to the Sept CTP.  I also am using ScreenSpaceLines3D for building the axes.
