Schematician's Goggles

This mod adds Schematician's Goggles, building off of Aviator's Goggles.

While Schematician's Goggles are equipped:

• The world becomes a Contraption Diagram.
• Looking at any sublevel shows its center of mass and live force vectors (lift, drag, thrust, gravity, etc.).
• The Aviator Goggle HUD (stress, burner output, etc.) is preserved.
• The schematic view can be toggled by right-clicking with the item in-hand.

The recipe is simple enough, just an iteration on the Aviator's Goggles.
