[REQ] "sort order" tags [#2915]

[sandpipers01]

I would like to be able to use MM to tag albums for sort order. For example, I manage my library with MM, but play it with PLEX, and would like to be able to set the album artist sort order, and the artist sort order. For example, have Bryan Adams sort as Adams, Bryan.
