german language file - wrong translation

[Cyclist]

I just want to tell you that in the german language files I discovered a wrong translation. The correct translation of Fnumber would be Blende. The espression FNummer isn't used in German.

Thanks for the report. Fixed in stable branch. The error was caused by the fact that I'm not a photographer, so I have little idea what all those technological terms meant - those I didn't know I left untranslated or translated them word-by-word.
