Merge branch 'comment-updated-by' into 'master'

Show who last edited a comment if it wasn't the original author

Fixes #1796.

The `updated_by` user is also tracked for issues and merge requests, but it isn't currently shown, because "edited by Person" would give the idea that Person edited the description, while most updates to those are assignee/milestone/labels, in which case who made that change is already visible in the comments.

See merge request !1075
