[tz] Busingen revisited

Getting back to the main topic, I pushed Arthur's change to the
experimental tz repository on github, with minor changes for
consistency with the rest of the data, and an updated URL
(the old one got redirected).  This change uses
the name "Busingen" in comments as well as in the database.
I've seen it "Buesingen" in English-language texts, but
"Busingen" is also common and there is some advantage to
spelling it the same way in the comments as it is in the data.

+# From Tobias Conradi (2011-09-12):
+# Busingen <http://www.buesingen.de>, surrounded by the Swiss canton
+# Schaffhausen, did not start observing DST in 1980 as the rest of DE
+# (West Germany at that time) and DD (East Germany at that time) did.
+# DD merged into DE, the area is currently covered by code DE in ISO 3166-1,
+# which in turn is covered by the zone Europe/Berlin.
