Changed AppDirCache.cs so that when an update occurs it will delete all orphaned files and import only new files (instead of deleting all files and reimporting). This will make it keep information that have already been downloaded instead of deleting them.
Also fixed a minor bug with the thumbs that had Age of Empires.exe looking for Age of Empires II.jpg for its thumb (if it existed).
