Add turbulence example to 3D Particles demo (#1066)

Browse Source 
- Make the attractor in the example dynamic to better showcase its functionality,
  and add a visual representation to it.
- Tweak the appearance of attracted particles.
- Fix force field particle display (it wasn't using Local Coords as intended).
- Lower the sun angle to make the background darker (and particles easier to see).
