Cleaned up the game ID code:

Browse Source 
- The game ID is now obtained from ScummVM ID directly, not by converting Sierra's internal ID
- Moved the code which reads the internal Sierra ID inside the resource manager
- Moved the code which converts the internal Sierra ID to ScummVM's IDs together with the rest of the detection code
