text: Title: Multi-user conversations in a thread
  Body: Allow for the conversation system to send multiple users to GPT3 in the conversation history.
  
  For example, we should key the user based on their discord name and the conversations should look like this:
  
  {CONVERSATION CONTEXT PRE-TEXT}
  Kaveen: Hey!
  GPTie: Hello there Kaveen, how can I help?
  Bob: Hey GPTie!
  GPTie: Hey to you as well Bob!
  
  For the initial version of this, each message sent by any user should cause an API Request to happen. In later, and more sophisticated versions of this, I want the API request to happen 10 seconds after no conversation activity has happened, so that we don't have to make an individual request for each user's message, especially if the users are talking to each other and not GPTie.
