Add base url to chatgpt configuration

[evannorstrand-mp]

For people who are using OpenAI compatible APIs for local LLMs, being able to change the baseurl and add custom model names for the ChatGpt integration opens up a lot of flexibility.

The big issue right now is that Agent's don't allow "local llm" options.

I would love to use this tool, but it's lacking some key features right now.
