[Bf-committers] new dependencies for (spacenav / ndof / 3D mouse) support

[Mike Erwin]

There's a new option in the 3D mouse popup menu. It works in turntable
mode, and will work in trackball also after dinner.

Setting this option makes orbit unusable for me, but hopefully usable
for those of you who have your brains wired differently!
