- Removed the code which reads the SCI version string from the game executable in the fallback detector. We no longer use the actual SCI version string, and we can auto-detect a lot of features from the game resources now. The EXE version string was only used to display the detected SCI version in the console, which isn't very useful to us anymore.
- Added detection for PC and Amiga versions based on the game's detected view types. Still need to do detection for Mac and Atari ST versions
