add support for x/y/z axes. The built-in function is (still) a NOOP, but

aircraft can plug a custom function. This function can access all internal
variables of the ViewManager class. It can set me.{x,y,z}_offset, and also
add offsets to me.{heading,pitch,roll}_offset. Example:

dynamic_view.register_headshake(func {
        me.x_offset = rand() * 0.02;  # Parkinson effect
});

The advantage of this implementation is that it doesn't break MMB drag
functionality, and that is can be frozen by mouse movements.
