Bug 17877: Add the order's notes to the table

This patch adds the vendor and internal note from the acquisition order
to the subscription detail page

Test plan:
- Create an order from a subscription, fill the internal and vendor
notes
- Go to the subscription's detail page
- Confirm that the columns are displayed in the "Acquisition details"
table and contain the correct values
- Make sure the "Home › Administration › Columns settings" admin page
let you hide them by default (for those who will not need them).
