Spreadsheet: Use new format functions.

In a few places I also simplified a few format strings:

    -outln("{} item{}", items, items.size() == 1 ? ' ' : 's');
    +outln("{} item(s)", items);

In my opinion this is more readable and in some places it incorrectly
wrote '0 item' which is "fixed" now. In other places the placeholder
space looked weird.
