Permissions Commands

[conaticus]

/add permission [Command] [Role/Permission/User]

• Ideally discord commands & permissions should be listed in autocomplete if easily obtainable (if not then we won't include discord permissions)
• Adds role/permission/user to have permission to a command

/get permissions [Command]

• Existing commands will be listed in an enum
• Returns a bullet point list of all the permissions including roles, discord defined permissions and users

/remove permission [Command] [Permission]

• Autocomplete lists permissions existing to that command to be removed
• Removes the specified permission (that was already set) from the command

We need to interact with discord's command permissions API, but I'm hoping Discord.Net makes this pretty easy - this is so that unpermitted commands aren't shown.

Also commands should have a default permission in the database (whichever Discord permission is appropriate (e.g Permissions.Administrator for admin commands) - this will also be displayed in the autocomplete
