For *mode* = *quat* the force is applied along the axis obtained

In quat mode, this fix makes use of per-atom quaternions to take
into account the fact that the orientation can rotate and hence the
direction of the active force can change. The quaternion mode
direction of the active force can change. The quat mode
of this fix only works with atom\_style ellipsoid.
