New-Ks: minor additions/corrections to ywang's work:

- Add sign for line speed 20 (else no way to return to max line speed once set)
- When no distant signal info available (default), Ks displays green light (2 sections free)
- Normal and wall signals again signal maximum speed (persistent restriction can be given via line speed nouw)
