Bug 21446: Improve display of changed values on course reserves and show permanent location instead of cart

TO TEST:
1) Set ReturnToShelvingCart on.
2) Create a Course Reserve and make inactive.
3) Add an item, changing Item type, Collection code, Shelving
   location, and Holding library.
4) Note these four fields in the item list.
5) Activate course reserve.
6) Note subtle/no difference in these fiels in the list.
7) Check in the item.
8) Go back to course reserves and note that the cart is listed in the
   field instead of permanent location.
9) Deactivate course reserve.
10) Reset permanent location on item manually.
11) Apply patch.
12) Repeat steps 4-9 noting that the permanent location is showing
    instead of current location.
    Also, if a change is assigned to the item, the change AND
    the regular state always show.  The active state will be in
    bold.
