- use wrapper class instead of std::wstring (reduces mixing of strings/paths; allows safe+easy join via operator/ and convenient case-insensitive comparison via operator==, avoids NativePathFromString, similar to boost::filesystem) - NativePath -> OsPath - add hash and To/FromJSVal for Path - add TS_ASSERT_PATH_EQUALS - replace _wfopen_s with sys_OpenFile - remove obsolete SortFiles/Directories This was SVN commit r9107.
