Fix sheet creation to copy all sheets from our template

Nathan put a lot of word into this template sheet, so it was a shame
the sheets weren't all coming over. It turned out the only reason that
was the case is that the code has a hard-coded list of names of sheets
to copy, (and that, only because I haven't yet figured out the API for
enumerating sheets).

For now, just update the hardcoded list to match what's in the current
template.
