v3.1.0

- Feature: Listening IP and external IP can now be separated with `config ipv4 bind <bind_ipv4_addr>` and `config ipv4 external <external_ipv4_addr>` to help with properly setting up networking.
- Fixed: Session cookies (cookies with no expiry date set) are now correctly captured every time. There is no need to specify `:always` key modifier for `auth_tokens` to capture them.
- Fixed: Captured custom tokens are now displayed properly and values are not truncated.
