[FR] Treat Reference as First Selection for Some Duplicate File Actions

[Servinjesus1]

In some actions (namely symlink and hardlink) for duplication handling, the action requires a Primary (first selection in group) and Secondaries (remaining selections per group) to perform the action. When using Reference Folders, the reference cannot be selected, but should be treated as the primary. Of course this should only apply to things like symlinking and hardlinking where data isn't lost, and not to deletion/moving where the idea of primary and secondary doesn't apply.

Currently attempting to deduplicate using references allows only one record to be selected per group so these records can't be symlinked to the reference they are duplicates of.

This is a rather essential feature for me because using references allows me to ignore internal duplicates I might not want to touch. In other words, I can use one folder as a reference to deduplicate another even if the folders contain self-duplicates.

While I can delete these duplicates, it would be nice to symlink them instead on the off chance I accidentally delete a duplicate that I actually want to keep. Seeing links, I feel safer deleting those one by one rather than having a program bulk delete things for me.
