Rewrote and greatly simplified the SAGA detector, removing many duplicate and unneeded entries

- Digital music will now always be enabled for all versions if the digital music file is present. The duplicate game entries with and without this file have been removed
- Changed the way compressed sound files are detected. All the duplicate compressed sound entries have been removed
- The Wyrmkeep Windows CD version is now properly distinguished from the DOS CD version
- Unified all the different patch file entries (apart from the Mac patch file entries, which are of a different type). If a patch file is not found, it's ignored
