Bug 21966: Fix descriptions of acquisition permissions to be more clear (again)

Bug 21966: Fix descriptions of acquisition permissions to be more clear (again)

This was already done and pushed on bug 3849, but some of it got
undone accidentally by a later patch.

To test:
- Check the acquisition permissions
- The *budget* permissions should clearly describe their
  use for 'funds'.
