Bug fix #32806

In 2.64, input for using an NDOF device included all 6 DOFs - including panning.
That makes using it for many people (including beginners like me) too hard, you
very quickly lose the 3d view rotation pivot, as if you are in free fly mode.

Fredrik provided an updated patch, which restores the 2.63 method to only
dolly and rotate by default. The new "all dof" operator is hidden in the keymaps
behind modifier keys SHIFT + CTRL. Users can set this in their configs of course.

As usual, we should be careful changing accepted defaults, and provide new
options as additional choice only.

A useful todo is to make user preference "around selection" work well.
Will check on this now too.
