[MERGED PR] Cyborg movement speed rebalance

[444explorer]

My usual build is Screenhead + Light Parts. Yeah I know, no treads on RP? Impossible! Jokes aside I haven't noticed much of a difference at all and I'd consider this a positive - change seems to be targeting the actual issues with borg speed (treads being too fast, heavy being too slow) without interfering with speeds I previously found to be completely fine to play against & with (Screenhead + Light, no treads or Speed Upgrade). So far has seemed good imo!
