MP1-4068 Added silent new movie scan (only for new added videos in shares which are marked to scan in configuration).
MP will every 5 minutes check queued files table for new entries and will add (scan) silently files to movie database (it will not scan if user watches video and will try it later when player is not in use for videos).
This is just tryout idea and nothing is configurable for now (except shares settings which already exist in MP.
