norwegian sentence disambiguation should not show up as segeju

If I open Norweigan on apertium.org there's Segeju as translation option that doesn't work. IRC says:

```
04:46 +Flammie> what's nor-seg? it appears on my apertium.org non-beta like so:
https://apertium.org/index.eng.html#?dir=nob-seg&q=hva%20er%20det
07:51 Unhammer> Flammie: probably a debug mode that's not meant to be installed
07:52 begiak> apertium-nno: marihauge [ 3fa6901 ] apertium-nno.nno.dix: NNO: Ramstein, Engamo,
varmblodsløp
07:52 Unhammer> Seg is for sentence disambiguation
07:52 Unhammer> "3. april" vs "3. Ny setning"
```

(also apertium.org should really just have link to github issues here, no?)
