dep/anitomy: port to use UCS-4 rather than wide strings rationale: wide strings are not the same on every platform, and might not even be Unicode. (while they usually are, its possible that they are not) I was *going* to change StringToInt to use a string stream, but outputting to an integer doesn't seem to work at all with UCS-4, even though it ought to, so I just rolled my own that uses the arabic digits only.

There are no changes divergent from any of the original files.
