Correctly override the equals method

VictimsRecord didn't correctly override the Object.equals method. This
stopped it from working correctly with things like:

    aList.containsAll(Collection<VictimsRecord> records);
Added negative test case to containsAll using additional
canned data.
Add default algorithm support. Default value is SHA512.
Multiple fixes in VictimsRecord

- add containsAll implementation
- formating fixes
- equal now handles combined hash matching
Equality should correctly handle cases where one of the combined hashes is empty
Reorganize testdata and add new resource.
Update VictimsRecordTest to test new methods. Refactor some bits.
Fix typo in resource file path
