[MERGED PR] Cyborg movement speed rebalance

[Mordent]

Looking at the before/after stated numbers, it looks like having light arms vs. no arms should actually increase a cyborg's speed, but I don't think that's what I've observed before (i.e. no arms is faster than light arms). Given that my understanding there based on that observation is flawed, could you clarify how a no-armed light cyborg with treads works, speed-wise?
