v3.0.0

- Feature: TLS certificates from LetsEncrypt will now get automatically renewed.
- Feature: Automated retrieval and renewal of LetsEncrypt TLS certificates is now managed by `certmagic` library.
- Feature: Authentication tokens can now be captured not only from cookies, but also from response body and HTTP headers.
- Feature: Phishing pages can now be embedded inside of iframes.
- Feature: Changed redirection after successful session capture from `Location` header redirection to injected Javascript redirection.
- Feature: Changed config file from `config.yaml` to `config.json`, permanently changing the configuration format to JSON.
- Feature: Changed open-source license from GPL to BSD-3.
- Feature: Added `always` modifier for capturing authentication cookies, forcing to capture a cookie even if it has no expiration time.
- Feature: Added `phishlet <phishlet>` command to show details of a specific phishlet.
- Feature: Added phishlet templates, allowing to create child phishlets with custom parameters like pre-configured subdomain or domain. Parameters can be defined anywhere in the phishlet file as `{param_name}` and every occurence will be replaced with pre-configured parameter values of the created child phishlet.
- Feature: Added `phishlet create` command to create child phishlets from template phishlets.
- Feature: Renamed lure `templates` to lure `redirectors` due to name conflict with phishlet templates.

- Feature: Added `{basedomain}` and `{basedomain_regexp}` support for `sub_filters` phishlet setting.
- Fixed: One target can now have multiple phishing sessions active for several different phishlets.
- Fixed: Cookie capture from HTTP packet response will not stop mid-term, ignoring missing `opt` cookies, when all authentication cookies are already captured.
- Fixed: `trigger_paths` regexp will now match a full string instead of triggering true when just part of it is detected in URL path.
- Fixed: Phishlet table rows are now sorted alphabetically.
- Fixed: Improved phishing session management to always create a new session when lure URL is hit if session cookie is not present, even when IP whitelist is set.
- Fixed: WebSocket connections are now properly proxied.
