Addon: Search for duplicate files

[SpraxDev]

Users should be able to search for duplicate files in a list of directories.

The user is able to:

• [ ] select the comparison method
  • [ ] file name (pattern)
  • [ ] md5
  • [ ] sha1, sha256, sha512
  • [ ] dHash (images only)
  • [ ] pHash (images only)
  • [ ] bit identical
• [ ] Configure a p% deciding when two files should be listed as identical
• [ ] Select files that have been found, preview them and delete or move them
• [ ] Select files based on a filter (e.g. all files whose path does not start/contain X, file size, modification/creation date, image dimensions, ...)
• [ ] The search result is temporarily saved, so it can be used again in the next morning
  • [ ] Possible to rescan already found files and check if they are still identical
