Subject: Bhop: uni-directional auto-strafe for all movement directions

- derive the desired air direction from the raw W/S/A/D input (view-relative)
- pick the velocity perpendicular that rotates toward that target, so S/A/D
  work instead of only forward and A/D no longer spin in circles
- no keys: accelerate along the crosshair
- menu label now "Uni-directional auto-strafe"; state column moved to x=270
