[MERGED PR] Cyborg movement speed rebalance

[Ikea]

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?

Each lost arms applies a -.4 movement modifier. For old behavior, for light with treads this means a speed of .5, for new behavior light with treads armless coincidentally also goes a speed of .5. Base armless light borg will end up going a bit faster (1.0 to 0.7). It may not be a bad idea to reduce this buff to something like -.2/.15 in order to make part targeting arms more viable, though Ill leave that call for others (for now) (Also losing a leg modifies your speed by 3.5, changing this to like 1 in order to make losing a leg still technically escapable without teleportation could be good as well)
