Improved Metadata fetching for Movies

It’d be great if the Infuse could check the containing folder name if the online movie metadata could not be found. Usually different releases uses short name for file name, or starts with the release team name. But the folder name always uses the normal name, included the release year. It’d be much easier if the file name could be remain the same. Now it’d be changed, or a lot of movies should be corrected manually if a metadata database rebuild happens.
