support for 3Dconnexion SpaceNavigator

Do count me in for supporting SpaceMouse with a plugin. The ability to smoothly translate/rotate a 3D scene is not only such a huge time saver, it provides the 3D info to your brain via motion parallax so essential to remaining oriented in real time in a 3D scene via a 2D monitor. Speaking of which, ideally there’d be support for side-by-side output to a 3D monitor, taking the same point further, but for starters, please, support 3Dconnexion’s SpaceMouse.
