- client api:
- added 'create_new_file_ids' parameter to the 'file_metadata' call. this governs whether the client should make a new database entry and file_id when you ask about hashes it has never seen before. it defaults to false, which is a change on previous behaviour
- added help talking about this
- added a unit test to test this
- added archive timestamp and hash hex sort enum definitions to the 'search_files' client api help
- client api version is now 31

next week

Next week is cleanup. Nothing too exciting, but I'd like to break the database code up a bit more.
