Make MND display depend on O2 narcotic preference
A while ago, we introduced a preference whether O2 should
be considered narcotic. We used this when computing
best mix or when entering the He content via MND. But
we forgot to make the displayed MND depend on this
preference. This patch add this.
Fixes #2895
