Motivation

This is to allow admin users to alter the permission for other non-admin users to be either:

Plan

Add a new command: modify

Usage:

modify permission {username} {user/mod/admin}
As a security precaution, {username} must be an exact match, close matches not allowed.
As a security precaution, admins cannot be set to a non-admin status. This will require manually editing the users file.
If {username} is not found, it should prompt the admin to search offline users, and if so, will search the offline user files and update there.
A prompt/confirmation will confirm the character name AND login username being (up/down)graded.
