[tz] Backzone entry for Europe/Vaduz

[Alois Treindl]

In the year 2013 I had contributed information that Swiss neighbor 
country Liechtenstein, represented by Europe/Vaduz in file backzone, did 
not have daylight saving time in 1941 and 1942, while Switzerland, 
represented by Europe/Zurich, did have it.

A colleague sent me a follow-up question today, which cause me to 
reconsider the question.

I was able to access the online archive of the Vaduz paper Vaterland for 
free - they offer a special summer deal.

I could confirm frm the paper that Liechtenstein did in fact follow the 
same DST in 1941 and 1942 as Switzerland did.

The entry Europe/Vaduz in the file backzone can be removed, so that the 
link Europe/Zurich Europe/Vaduz remains effective even for those who, 
like me, compile TZ with backzone included.

I attach a few newspaper clippings, not translated.
