Comment 5 for bug 1730752

My signoff is available at http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/kmlussier/lp1730752-eg-grid-columns-dialog-signoff

Although it's targeted to 3.0, it might also be considered a new feature, so I'm leaving it for the 3.0 release maintainer to make that determination.
