Bug 10225 - If an item isn't editable, don't show the onclick Edit/Delete menu

The user should not be shown edit/delete links when clicking on a row in
additems which they cannot edit because of the IndependantBranches
setting. This patch adds a class to the row to exclude such rows in the
JavaScript onclick handler.

To test:

- Turn IndependantBranches on and edit items for a title which
  has holdings from various branches including your own.
- Click a row for an item which is held by your library. You should see
  the "Edit/Delete" links appear.
- Click a row for an item which is held by another library. No links
  should appear.
