  Clean Admin commands, removing all unnecessary or unused code.
  Small typo fixes.
  Remove all unused `use` definitions.
  Remove any unnecessary code from commands. Changes include: - Removed the definitions of member variables that had the same values as their inherited defaults. These can be removed since the default values apply anyway. - Removed superfluous code form execute command.
