Rename multiple torrents w/ search and replace functionality

[FurkanKambay]

Just an idea, let me know if you think this is useful.

Say we have a lot of torrents with a scene tag at the end "[scene]", keywords like 1080p, hevc, etc. and let's not forget most torrents use periods instead of space. Personally, I like to remove the clutter from these to keep a tidy and readable torrent list.

We could implement a search and replace feature (and maybe regex) to rename multiple torrents at a time. Another idea is to define some rename rules so each torrent that gets added goes through those rules. ("remove anything in square brackets at the end" type stuff)

While writing this, I thought of something else. We can also assign tags to torrents based on their name. If it has "1080p" or "FHD" in its name, remove it and assign the tag 1080p. Sonarr has this.
