sometimes 'exit' would be called before 'close', and 'close' didn't do the safety check 'exit' did, making `--running` run twice; additionally, proc.exitCode was always null, check codeOrError instead from the proc.on callback
- rate limit is stderr, so need to check to make sure only finishing on other errors
- color errors in log
- log errors to userDb
- use fallback date in case dates weren't logged (e.g. /media failed)
- report on not-found users, which may indicate a username change or deleted account
- report on authorization errors
