Move user role data to DB and organize color roles

[Zentiph]

Color roles as of now are created using the user's ID. This can get messy and bloat the roles of a server if there's a lot of members. Instead, the system should be updated to:

• Only keep roles that are actively being used, and delete unused color roles
• Create roles by hex color instead of by user ID, and assign users with the same color the same role
  • Then, to associate each user with their color role, store that data in a user data DB

These changes will minimize role bloat and better organize color roles.
