Added
- Added `add` and `subtract` to `/jails set duration <player> <time>`. Staff can now add time to the time a prisoner has left, or remove time from it.
- Added signed time to `/jails set duration`. A plus sign adds time, for example `+15m`. A minus sign removes time, for example `-10m`.
- Added tab completion for `set`, `add`, `subtract`, and time examples at `/jails set duration <player>`.
- Added a handcuff escort. Staff with the `jails.handcuff` permission right-click a handcuffed player with an empty hand to lead the prisoner. A second right-click stops the escort.
- The escort stops when the prisoner is unhandcuffed, jailed, disconnected, or in another world than the officer.
- When the removed time is equal to or more than the time left, the prisoner leaves jail at once. Staff and the prisoner each get a message.
- Added escort messages in the 7 supported languages.
- Added the escort options to `config.yml` under `handcuff-settings.escort`: `enabled`, `max-distance`, `follow-distance`, and `check-interval
