Show an archived row in place after archiving a link in multi-link field

Idea that was originally raised in #245 (comment)

When archiving a link, replace the deleted link with an "Archived" row which fades the row out after a few seconds

Not sure if we still want to do this. As part of this PR focus will go to the next link in the list when a link is archived, having both of these approaches in tandem may be too much
