its tiles are loaded from the same directory.
- RFF files now load their entire directories into the lumplist.
- Added char * and const char * type coversions for FString, so FStrings can be
freely passed to functions expecting C strings. (Except varargs functions,
which still require manually fetching the C string out of it.)
- Renamed the name class to FName.
- Renamed the string class to FString to emphasize that it is not std::string.
