Navigation: an NX mouse mapping (#10156)

* Navigation: an NX mouse mapping

NX's CAD1 scheme drags the middle button to rotate, middle + left to zoom and
middle + right to pan. The mouse mappings here hold one button at a time, so
the preset takes the middle drag with Shift (pan) and Ctrl (zoom) for those two
drags, leaves the right button to the context menu, and fits on a middle
double-click as NX does.

The help text says which NX drags the modifiers stand for.
