Without --since, fetcher service and job-search serve start each source from the newest release stored for it (the new store.LatestReleaseDate, by Source), so a restart carries on where it left off instead of fetching the last day again; with nothing stored, the client's default still applies. --since overrides it for every source. The Find a Tender source's name is now a constant, as the Source its opportunities are stored with. The README's guide to adding a source is brought up to date with the current worker, start and config type names.
