add message queue system

thinking about redis visits don't save properly because, to make less requests to the DB, visits are also being stored and calculated locally in a DB._visits variable. this causes problems when there is more than 1 gunicorn worker since their visit counts are not synchronized. so now im running at 1 worker yey

One worker?

a worker is a separate instance of the whole app
