Transferred this issue to Modmail. Modmail currently does not store any messages from bots, so this'll need to be implemented here before adding to the logviewer.

A problem with storing bot responses is that we'll need to store embeds alongside the message. This means that the database format may need to be altered.

@Taaku18 Could end up having the bot messages stored as a raw message unless we are feeling fancy and adding embeds too.
