LP#1778083 Location, Floating, and Age Protect missing from Items Out

Adds columns for Location (Copy), Floating Group, and Age-based Hold
Protection to the items out grid.

To test.
1. View an items out screen to see that the Location, Floating Group,
   and Age-based Hold protection columns are not available as options.
2. Apply the patch.
3. Edit some items and add definitions for Floating Group, and
   Age-based hold protection.
4. Check out these items and other items that do not have a floating
   group or age-based protection.
5. Display the Location, Floating Group, and Age-based Hold Protection
   columns.
