"Albums not yet part of the wiki" section for groups

[towerofnix]

Currently it's pretty easy for someone coming by the wiki to just assume that we're totally comprehensive about the discographies we've added as groups — or at least up til the latest released album on the wiki. But we often aren't! And the wiki doesn't reflect that info at all.

It would be good to have a section at the end of a group's info page, listing all the albums or releases we're aware of that would fit with that group, but aren't yet on the wiki. Sort of like the album additions list, but focused on just the bare essentials - the date, name, and link.

It might be reasonable to allow a sort of sectioning here. Like additional files - at the chunk level you have name of section and optional description, and at the row level you have name of album, date of album, and (probably) one URL.

Although it's secondary to the actual album list, we do want to make it clear that this is an extant section on the page. Might be good, on the group info page, to include a paragraph with a link that jumps to the section—not sure the phrasing exactly. But part of the same paragraph as "Browse listings for this group." and all that.
