Bug 22090: Add missing information to cash register CSV file

Some information was missing from the CSV export file
of the Cash register report: manager surname, patron surname
and payment notes.

Also pretties up the column headers a bit and makes the
sequence between GUI and CSV export match.

To test:
- Make sure you have some fines and fees and payments in
  your system
- Make a search with the Cash register report
- Export results as CSV
- Proof read hader line and make sure contents match headings
- Verify first name and surname are shown for manager and patron
- Verify notes show up
