Finally have VRPN compiling, and some code using it in

SimMedTK is using VRPN compiling properly.
Most of the VRPN stuff is compiling, but linking has some issues.
Somehow VRPN is adding libs that doesn't exist to the VS project for
linking. WIP Adds basic reading functionality from a networked
phantom omni.  Some misc changes happened in this commitsuch as some
namespace changes and framework start up and shutdown flow. Added a
vrpnPhantomController.  Abstracted out renderCube a little because
it gets used in other places. Fixed a few compiler warnings
