Create a trust system for new users

[Hona]

Something like 10+ messages and 3+ days before being able to send media

[Gocnak]

And do not give them the role if they have a "blacklist" role already -- the "send media" part comes from getting the "trusted" role, but we also have an "untrustworthy" role that would be given to potentially problematic people that should never be "trusted".

Completion Checklist:

• [ ] On every message received, store the message count for each day, user, channel - maybe MySQL or Postgres
• [ ] After incrementing the user count, if they don't have the 'Trusted' or the 'Blacklist' role, and if they have been in the server for 3+ days, SUM the total messages for the user. If its > 10, give them the role.
• [ ] Add a command for making a user 'Blacklist'ed

This solution should also allow for analytics of user activity, without storing all messages (don't want to store messages for sake of privacy).
