Hide certain commands from slash menu

[pkdev08]

Lets say you have a multi-purpose bot with a ton of features/categories, but a certain guild only needs one feature. It would be useful for them to be able to hide the remaining commands they don't need to avoid clutter in the slash menu. This was recommended by one of my bot users, and I agree this would be helpful. As of right now, you can hide them from other members, but there's no option for server admins to hide them from themselves.
