 - Adds in subscription based roles which renew every customized interval.
 - Allows settings messages through DM to users who obtain a specific role (such as role info).
 - Renames srole to selfrole and removes Red's default selfrole.
-**In progress:**
 - Makes listing roles a bit prettier.
 - Allow setting roles to automatically add on guild join.
 - Enhance exclusive roles, allow setting custom role groups where the bot enforces only one role to be on a user at a time, even if it isn't a selfrole. The bot will automatically remove the old role if a new role from the same group is added. Also lists name of role group in list command to make it clearer.
