GPT-3 Gopher

This implements a conversation with GPT-3 or Jurassic 1. It adds a prompt to keep the conversation friendly and adds the recent conversation (or a designed one if the conversation is new). You can use any of the 4 GPT-3 models or either of the 2 Jurassic 1 models and adjust the options.

An API key from openai.com is necessary for GPT-3 and a key from ai21.com for the Jurassic 1 models.
