Issue

Description

It would be useful if we could build a middleware cog which logged all bot activity, and errors, to syslog.
This would allow us to feed it into a platform such as Graylog, and provide somewhere where we could search for actions in a more useful way than Discord's search
(e.g.:

message_sender: tigattack AND action_type: auto_delete

could return all messages by user tigattack that the bot had to automatically delete)

DoD

Create a middleware cog that logs all bot actions and console messages to a syslog server
