v1.2.4 patch release with Gradio UI

[operand]

Summary of changes:

Demo changes:

• Replaced the React based UI with a Gradio UI in demos.
• Renamed WebApp class to ReactApp.
• Moved both app implementations (Gradio, React) to the
  ./examples/demo/apps directory.
• Simplified demos to only include the Host and OpenAIFunctionAgent by
  default for a better initial experience.
• Moved agent mixins (HelpMethods, PromptMethods) to a ./mixins subdirectory
• Simplified AMQP demo environment to only use two application containers.
• Update documentation as needed

Notes:

I'm excited to add a Gradio UI!

To implement the chat interface I used Gradio's Chatbot component. It supports some limited markdown formatting, making the output look a lot nicer especially when there are code samples. The downside was that I had to use a form of polling to get the UI to update on new messages, and write some custom css to make it look nicer. But hopefully we can improve this more along the way.

Streaming output is not yet implemented but is possible. I'll be adding a separate issue for that.

As far as being a base for multimodal features - The chatbot already supports display of some multimedia content, though this is not yet implemented in the demo. So I think it's a good foundation to start and we can experiment with using components alongside the chat component for more complex interactions when multimodal features are added.

As always I'm eager to hear your thoughts if you have any. Thanks!
