Bug 7639: add option to forgive overdue fines when declaring items lost

This patch adds functionality to forgive overdue fine when an item is
set to lost status.  Fines are forgiven only when the syspref
WhenLostForgiveFine is set to yes. Item can be set to lost status from:

- catalogue/moredetail.pl
- cataloguing/additem.pl
- tools/batchMod.pl
- misc/cronjobs/longoverdue.pl

Changed subroutine C4::Circulation::LostItem to forgive fines on the
item depending on the value of syspref WhenLostForgiveFine. This
routine is currently used to return an item and charge a replacement
cost.

Also added a new syspref in C4::Circulation::LostItem -
WhenLostChargeReplacementFee.  The replacement fee will now be charged
only if this syspref is set to yes.  The default value of the
WhenLostChargeReplacementFee is yes, meaning that current behavior
will not change during upgrade.
