New string in nautilus marked for translation

[Martin Wehner <martin wehner gmail com>]

I just had to commit a patch which marks two strings for translation
which previously weren't: "Search" and "Search for %s" in
nautilus-query.c (which was added to POTFILES.in).
"Search" is already translated in another file, so it doesn't really
count I guess.
