Tagging classical music

[Mike48]

I forgot to mention:

- Judging from the tags output file written by Minim, JRMC transmits the Artist list as multiple instances, not as a list (though it's stored as a list).

- I have added a "Subgenre" field, though I am not finding it useful.

- I use the genre "Classical guitar" as different in character from "Classical," which includes chamber, orchestral, other solo, etc. I haven't decided whether to make "Opera" a separate genre, but probably so.

- In thinking about it, People may still be a useful tag. For example, to list the personnel when the artist is the Tokyo Quartet.
