/audit command to list admin actions

[DecentralizedDan]

Mods in general and security teams in particular need a way to lookup actions taking by admins

• /audit will show the last total 100 Bouncer admin actions
  • /audit {n} will show the last n Bouncer admin actions
  • choosing an n that is not an integer, or is less than 1, or more than 10K, will result in "Error: This number is out of bounds"
• /audit @{mod} will show all of that mod's admin actions
  • If there are 0 actions for a mod, show: "This mod has not executed any Bouncer commands"
  • Listing more than one mod name will result in: "Error: Can only show one mod's actions at a time"
  • Listing a non-mod's name will result in: "Error: Audit only works with mods who can run Bouncer actions"
