Show more info when asking about duplicated album

[pescuma]

When asking the user to choose what to do with duplicated albums, it would be helpful to show the differences in more fields, if available.

Original text:

When importing albums with same artist and album names, but different years, the importer says that they are the same and shows the list of olds and new:

Old: 12 items, MP3, 192kbps, 35:10
Old: 12 items, MP3, 155kbps, 41:39
Old: 13 items, MP3, 192kbps, 41:04
New: 7 items, MP3, 160kbps, 35:52

I'd like to ask for 2 features here:

1. Show also the album names, as configured in list_format_album
2. Do not assume the albums are the same when the year changes

Interesting issue!

• This wouldn't be tremendously useful in the default configuration. But I understand the motivation—maybe we should just show a few of the standard disambiguator fields, like year, media, and catalog number, if they differ among the releases.
• I'm not sure about weakening the duplicate detection to distinguish albums of different years. If anything, we would do a general configurable list of fields that define duplicates.

This seems like two separate issues. Care to open a new one for one or the other?

Awesome; thanks.

1. Show also the album names, as configured in list_format_album

While we wait for #1133 is it possible to have item 1. implemented?
