fixed bug with queueLoginTime not being reset when the player attempted a login
direct integration with mcbans, avoid a banned player waiting in the queue. will result in mcbans spam when player first tries to join, but caches ban status after that to avoid future spam
implemented perm-based queueLoginTime
implemented /offduty, /onduty, to allow online mods to go OffDuty. for the requiredPermsOnline, any flagged as offduty is not counted.
fixed a bug related to limitExemptPerms not working properly
