* parsing of action in jail-configs considers space between action-names as separator also
(previously only new-line was allowed), for example `action = a b` would specify 2 actions `a` and `b`
* new filter and jail for GitLab recognizing failed application logins (gh-2689)
* new filter and jail for SoftEtherVPN recognizing failed application logins (gh-2723)
* `filter.d/guacamole.conf` extended with `logging` parameter to follow webapp-logging if it's configured (gh-2631)
* introduced new prefix `{UNB}` for `datepattern` to disable word boundaries in regex;
* datetemplate: improved anchor detection for capturing groups `(^...)`;
