Latest version of the PhysX engine is now integrated into the project (n...

...o instancing)

****If this breaks for anybody, please let me know****

Picking now works for PhysX (though it may be a bit hard to grab cubes, aim for the top and avoid the immovable cube at 0,0,0; this is on my fixit list)

Our scene now loads up by default

Mouse now stays in the center, though unhidden. Picking is done from the mouse pointer

Controls have changed a bit:
Shift: Move Up
Control: Move Down
E: Toggle Freezing an object in place
G: Toggle Turning an object into a gravity generator
C: Cycle through the 5 groups on a cube
Left Click: Picks up an object

E,G,and C all work whether your pointing at objects or already have one picked up (in which it will first be applied to the object currently held)
