v2.6:
- Trap all null errors in tab-complete from malformed data.
- Added Russian translation courtesy of l1ttleO.
- Add compatibility back for pre 1.14 (not tested any further back than 1.8).
- Fix a bug in manuaddv throwing an error.
- Prefix/suffix will now be fetched from subgroups if there is no value on the player or the main group.
- Added a new config entry for tab_validate. If true GM will offer tab-complete names obeying the validate_toggle setting.
- Implement the unused GMUserEvent - USER_PERMISSIONS_CHANGED. This will trigger whenever an Online player has their permissions updated.
- Register the main GroupManager class with Bukkits ServiceManager instead of the WorldsHolder.
- Stop non UUID users in the users.yml from preventing superperm updates.
