New Relation option for 'different' editions of the same series.

[ocgineer]

Created issue as per request via Discord.

For people that keep the different published editions and like to have them both in Kavita, to link them together with relationships my proposal would be to add an additional relationship like Alternate Edition, Other Edition, or simply Edition.

Preferably the relationship should not show 'Parent' as there is no real parent here. It would be best for users to set-up the other edition similar to prequel/sequel (if automatic does not allow this) so that whenever the user checks either of the edition the user can see other edition always in the relations tab.

With this extra relation option, users can use this for, but not limited to;

• Normal published <> Omnibus published
• Special Edition Anniversary Edition
• Expired License <> New License (re)published
• Black & White <> Color Edition
• Official <> Scanlation

The current available relation option do not convey that it is a different edition. Alternate Version which is the closest would be more used to link Manga with the Light Novel, as the format is different but basically the same story. With different Editions only slight changes are made, like translation or colorization while the story is exactly the same.
