[Cuis] Wrapper for file access in different Smalltalk dialects

Hi Masashi,

I was trying FileMan tests today and I saw they create some folders in 
my drive. The names looked a bit strange, so I took a closer look and 
found a couple of bugs. At least on Windows, #testRecursiveDelete 
instead of creating
       subDir/aaa/bbb/ccc/ddd/eee/fff/ggg/test1
it created
        subDir/bbb/ccc/eee/ggg/test!

So I wrote a few more tests on the issues I saw, and teaked the code to 
make them pass. The result is attached, and I think is useful for all 
ports of FileMan.

Thanks,
Juan Vuletich
