[MERGED PR] Cyborg movement speed rebalance

[DasBrain]

As a borg player, I was skeptical about the entire premise of this: That borgs are too fast.
I do not think this is the case. But hey, that is just my opinion.

I subjectively see less borg players now that those changes are test merged - which is a good indicator for me that other borg players do not like those changes either.

Now it feels that borgs with treads and screen head are just as fast as a non-sprinting human - but unlike humans, borgs can not sprint.
So their base speed should be higher to offset that.
