Updated version.
Upped timout value for archivertest, as it never runs within time on my laptop... And sometimes failes on Jenkins.
Added proto folder to protobuf generation.

Added WriteReport as return by Slot.write.
 - This will enable SimpleArchiver to write metadata files.
 - Other Archiver plugins might also be able to utilize this in the future.
Added finals, organized imports and simplified a few statements.
Added MetadataHandler for use with replay.
