Performer merge
Fixes #1351. (The issue is about both performers and scenes, but scene merging was implemented some time ago.)
Also includes (as separate commits) some changes to make the UI of the different merge types consistent, although there's still a difference for scenes, where there's a convenient drop-down, so adding it there seemed preferable to adding a dedicated button.
No tests, and while it worked for me, I don't think that's complete enough coverage of all the fields to call it good. I could probably work on some tests if it generally looks good.

I think this could potentially be a good addition. I know it is currently supported via plugins but since scenes can do it then might be good for performers. Haven't really looked at the code and there are conflicts to take care of.
Just an additional testing note: merging from the performers page redirected to the scene list filtering on the destination performer, but showing the performer id rather than the name.
