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.
- Update AMEC's getFileProps (changes related to MacResMan)
- This commit also includes a change from other engines.
- Fallback detection here depends upon many Engine resources.
- As such, it might not be suitable to add all of them to executable.
- Thus, shift fallback detection to the dynamic part.
- The static part gets the relevant Engine plugin & then tries to call it.
- This way, fallback detection for Wintermute will depend on the engine plugin.
- Normal detection will still work fine.
