[Suggestion] Confirmation when running !cleanup delete without parameters

[LordTylus]

Hello there,

last night one of our admins had a bit too much fun cleaning on the server so that he accidentally ran !cleanup delete without any parameters.

This well. didnt end so well because cleanup is very thorough and deleted just about every grid on the server.

This poses a risk of accidents so I would like to make it more secure:

So the suggestion would be to:

!cleanup delete
server: Are you sure you want to delete ALL grids form the server? If so confirm by repeating the command
!cleanup delete
server: You wished for it. Your world now goes poof

Alternatively cleanup delete would require a parameter always. And If one wants to delete EVERYTHING they would need to do

!cleanup delete all
