Bug 22014: Add ability to send "00" in SIP CV field on checkin success

Some SIP devices ( in this particular case, bin sorting machines from RFID Library Solutions ) require a checkin success to return a CV field of the value "00" rather than no CV field at all. Koha should be able to support this behavior.

Test Plan:
1) Apply this patch
2) Enable the new option cv_send_00_on_success for a SIP2 account
3) Restart SIP
4) Check in an item successfully via SIP
5) Note the response contains a CV field with the value '00'
