Bug 18952: Add internal note to acq details tab

Any important notes about an order are usually added to the
internal note. This patch makes the note visible on the
acq detail tab in the staff client.

To test:
- Add a basket
- Order something
- Add an internal note for the order
- Go to the detail page of the ordered record
- Switch to the Acquisition details tab
- Verify that with the patch the internal note shows
- Verify that the new column can be toggled using the
  column visibility settings
