WebUI: Add ability to add/remove tracker from selected torrents

[userwiths]

Closes #22618.

Currently, I believe, the API for tracker addition/removal supports either one torrent (torrent's Id is passed in hash argument) or all torrents (hash is *).

The proposed changes allow for the passing of a list of hashes separated by a |, just like we pass multiple trackers.

I'm not 100% sure how we approach api changes/tweaks, so I expect there are steps ive probably missed (api version bump?). Would be happy to address them if someone points them out.

@userwiths In case you missed this comment.

Soooo we keep using * in removeTrackersAction but use all in addTrackersAction ? Because removeTrackersAction used * since before and addTrackersAction is the new one i guess.

Ok changes coming in minute.

Also rebased because I saw there was a conflict with master.

That should be what you requested, we only pass all to applyToTorrents and never *.

Changes made to applyToTorrents() should also be reverted.
