Bug 7639: QA Followup - Fix update description

Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de>
With these patches we now have 3 preferences that deal with
fines/fees and lost items:

Replacement price
- On marking lost:  WhenLostChargeReplacementFee
- On return: RefundLostItemFeeOnReturn (preexisting)

Overdue fines
- On marking lost: WhenLostForgiveFine

System preferences work according to their description.

Further notes:
- Patches pass all tests and QA script.
- LostItem is changed and needs unit tests.
  All occurrences of LostItem have been changed.
- Database update is ok. I had to fix the sysprefs.sql
  file that has been recently rewritten and alphabetized.
