Dutch translation - missing texts and improvements

[gh471]

Some texts are missing (see inlang) like:

Dew point perception - best translated as Dauwpunt beleving

Comfortable is now translated as "gemakkelijk": IMHO this is not correct Dutch (at least in the north-western part of the Netherlands). Better would be: "comfortabel" or "aangenaam" or "behagelijk". I (native speaker) would prefer "aangenaam".

I could do the changes myself.

Best to ping @BebeMischa who did the original change #313 3fe1be1 from "aangenaam" to "behagelijk".

I think this thread can also be closed due to commit #362
