Add customizable roles

[Yousef-Bulbulia]

What problem are you facing?

Right now, the role names "admin" and "moderator" are hardcoded as the privileged roles of the bot. But other discord servers may have different names for the admin role and moderator role.

What can we do to fix that problem?

Allow the owner of the server to set which roles will be the admin and moderator roles. Admins should be able to remove or change the moderator role.

Some considerations I thought of:

1. Should we enable different permissions for different roles? If so, what permissions should be divided into levels?
2. What would the syntax be? !anon set role 1 @admin ? (1 would be some type of permission level perhaps)

1. I was thinking, maybe we could have 6 different levels:
   6: Set role permissions for the bot
   5: Set channels
   4: Permbans
   3: Add slurs
   2: Enable slowmode
   1: Tempbans, warns

   So, if a role is assigned to a level, then users with that role would have the permissions of that level, along with all of the levels below it.

2. I think that's a good syntax

Also, when the bot is added to a server, the owner should automatically have level 6 permissions, and from there they can set what roles get what permission levels.

One thing to consider is how this change would affect servers that already use the bot. Maybe for servers where the bot is already in use, we could just assign the owner level 6 permissions and everyone else would be left with no permissions. Then the owner could just assign roles to levels.
