New command to set a faction as permanent: /f permanent <faction tag> (requires new admin-level permission "factions.setPermanent"). Permanent factions will not be deleted if they have no members, and faction admins of such factions are allowed to leave without a replacement available. Faction admins are also unable to disband their own faction if it is Permanent; only those with the admin-level "factions.disband" permission can disband such a faction while it is set as Permanent.
