Rework/Re-add queue automatic muting

Rework Queue System muting

muting

• remove muting?
  • have some sort of migration period where we still keep unmuteling users
• let muting still work, but with channel permissions?
• Check if staging channel should change any of the behavior, do they have commands to put someone on stage? Then that should be done instead of muting/unmuting when its a staging channel

new/adjusted features

• DONE Allow all admins to manage Queue #276 as part of this?
• DONE another feature that sounded nice: the ability to prolong the length of the queue
  • maybe only usable <15mins before the end of the queue, so that it's not used without reason
  • maybe a limit on how often it can be used
