Movement speed should affect climbing

[asmallrabbit]

Currently the movement speed bonus does not apply when dupes are climbing cliffs etc. So unless you are travelling horizontally flat, or vertically straight, you will not see a benefit from movement speed. Really puts a damper on tunneling a natural incline/decline or when you have gaps they need to hop over etc, a 180% move speed and 0% move speed will climb an incline at the same speed exactly. Best layout becomes perfectly vertical and horizontal tunnels with as few interruptions as possible, which is kinda boring, I like creating different levels etc instead of giant boxes, but the more "switches" your dupes have to do, the more they slow down.
