Bux fix.
Fixed chat bug that started after OpenAI API update on April 17th.
Modified files js/app.js

Now it is possible to open a widget directly through a URL. When communicating with an oracle, a URL will be generated in the navigation bar, allowing you to access the oracle directly by sharing this link

Added new models:

• gpt-3.5-turbo-16k: Same capabilities as the standard gpt-3.5-turbo model but with 4 times the context. (16,384 tokens)
• gpt-4: More capable than any GPT-3.5 model, able to do more complex tasks (8,192 tokens)
• gpt-4-32k: Same capabilities as the base gpt-4 mode but with 4x the context length. Will be updated with our latest model iteration. (32,768 tokens)

A problem with the cancelSpeechSynthesis function that was failing in some browsers, specifically on line 1118 of the app.js file, has been fixed.

• Fix was performed on line 340 of the app.js file to correct the OpenAI error return when credits expire.
• Changes were made to the animals of power prompt, to improve the response experience

Now it is possible to download chat conversations in PDF format.
