Andy McFadden d23a3b1ad8 Replace place-holder strings 
The NufxLib and diskimg libraries want narrow strings for certain
things, notably for the "storage name", i.e. how the name will appear
on the disk image or in the file archive.  We need to convert from
Windows UTF-16 to an Apple II filesystem-specific 8-bit character
representation.

We used to just pass narrow strings all the way through, so we didn't
need any intermediate storage to hold the conversion.  Now we do.  In
some cases there's nowhere good to put it.  The initial UTF-16
conversion changes just dropped in some place-holder strings.

This corrects the behavior, though in a couple of cases we're adding
kluges on top of code that was already badly bent from its original
intent (as initially conceived, CiderPress wasn't going to handle disk
images, just ShrinkIt archives).  It's not pretty, but it should work
for now.

* fork tag on it. We need to compare the normalized filename before
* the ProDOS normalizer/uniqifier gets a chance to mangle it. As luck
* would have it, that's exactly what we have in "storageName".
