Bug 21882: Show price information in acqusitions tab on staff detail page

This adds a new 'Price' column to the acqusition details tab.

To test:
- Apply patch
- Add one or more orders for a record.
- Before closing the basket: go to the detail page in the catalog
- Verify that the price estimated/budgetet price now shows in a new column
- Add actual cost to the basket or close the basket and receive the item
- Verify the column now shows the updated actual cost
- Verfy the tooltip on the table heading works
- Verify the column configuration for the new column works as well
