For each engine:
- Make a new folder detection
- Move detection-related files inside the folder
- Add a new module "enginename/detection"
- Add DETECT_OBJS here
- Adjust the normal engine module to remove detect_objs
- Adjust every file for the new changes.
- Entire code was located in the main sword2.cpp file.
- Seperate detection-related code to detection.cpp
- Seperate other MetaEngineConnect related code to metaengine.cpp
- detection.h serves common code between the above files
- A enum value has been copied from sword2.h into the detection TU to avoid duplicate copy
- the detection.h has static function definitions for detecting games.
- This is because metaengine.cpp includes it & detection.cpp does as well.
- If we keep the methods as static, we can truely seperate out everything detection related.
