Guild Chest Fix 1.1.0

This update makes the save parser survive future game updates. The tool now reads sets, which fixes the error about SetProperty on InLockerCharacterInstanceIDArray from the latest game version. Any save data type the tool has never seen before is now carried through untouched instead of stopping with an error. A test suite now runs on every build so a broken parser cannot ship. As always the tool verifies every edit byte by byte and refuses to write anything unexpected.
