1.8.0 hint for velocity arrow scale

[Kilinich]

Velocity_Scale_Tooltip = "The velocity arrow indicates the distance the object will travel during this number of seconds. The unit, s, is equivalent to m/(m/s), i.e. distance per velocity."

Mean just: "Arrow length for speed of 1 m/s"

But someone will notice why the unit is "s", by current tooltip.
