Comment 4 for bug 1402770

Thanks Blake! I added Andrea's and my signoff to your commit. I also added a release notes entry and added another commit to make the new column picker option hidden in most item interfaces. It was displaying by default in the Check Out tab, In-House Use screen and other interfaces where the info might not be very useful to users. WIth this commit, it continues to display by default in the xul Items Out tab.
