DC++ Metadata for files, add additional information about the shared files

At moment you can search files based on filename, type, etc. What I am suggesting is that you can associate metadata with a particular file, some of the information can be gathered automatically, ie on a mp3 file by examining the ID3 tags. For the case of MP3 files, you could metadata for bitrate, album, group, genre. For movie files it might be source (tv rip,dvd rip,telecopy), actors, etc. If someone tags an file then when you search it can update the metadata for your own files if you don't have anything specified if someone else has provided the data.
