Upgrade Storageuse locale for date parsing
When adding an entry, standalone Zotero interprets "10.3.2013" for "Datum" in the German version as mm.dd.yyyy (the American way), but that should be dd.mm.yyyy (the German way). It's very likely that many users don't notice that problem as long as dd <= 12.

I agree it's quite annoying because it's indeed easy to miss on entry.
