This release enables `forum-dl` to be used to download files (in particular, images) from forums much like `gallery-dl` does for gallery sites.
- Embedded objects (images, audio, videos, etc.) are now downloaded
- Output to stdout by default (`-o -` is not necessary anymore)
- New options:
- `--files-output DIR` -- save all downloaded files in `DIR`
- `--no-files` -- disable saving of files
- `--outside-files` -- also save files outside posts (e.g. forum banners)
- `--timeout` -- set HTTP request timeout
