This updates GenericEntry's filename handling to be more careful about Mac OS Roman vs. Unicode. Most of the work is still done with a CP-1252 conversion instead of MOR, but we now do a proper conversion on the "display name", so we see the right thing in the content list and file viewer. Copy & paste, disk-to-file-archive, and file-archive-to-disk conversions should work (correctly) as before. Extracted files will still have "_" or "%AA" instead of a Unicode TRADE MARK SIGN, but that's fine for now -- we can extract and re-add the files losslessly. The filenames are now stored in CStrings rather than WCHAR*. Also, fixed a bad initializer in the file-archive-to-disk conversion dialog.
