CUP Compat - Fix NVG Black/Green translations

I've just taken a look at nightvision's stringtable - it's inconsistent, just like here, when it comes to color capitalisation.
In German, do we want to capitalise the colour or not?

I think I originally made these nvg translations by piecing together cup and vanilla words
vanilla stringtables are inconsistent
