ArchiveBox config definitons (including defaults and dynamic config options).
Config Usage Example:
archivebox config --set MEDIA_TIMEOUT=600
env MEDIA_TIMEOUT=600 USE_COLOR=False ... archivebox [subcommand] ...
Config Precedence Order:
1. cli args (--update-all / --index-only / etc.)
2. shell environment vars (env USE_COLOR=False archivebox add '...')
3. config file (echo "SAVE_FAVICON=False" >> ArchiveBox.conf)
4. defaults (defined below in Python)
