rename it llama electron and add support for all llama based models

[x-legion]

• Your project has lots of potential. I like the familiar looking chat interface.
• Sticking with just alpaca is limiting this repo's potential. Because there are a lots of finetuned llama models coming out each day.
• Also adding support for all ggml versions would be great like this . It would make your project more compatible and flexible.
• And the ability to change temperatures and other parameters would be great too. It would allow users to customize their chat experience and experiment with different settings.

I will consider changing the name to llama.

I won't try to add support for all ggml versions since llama.cpp itself doesn't support the old one. I don't want to put both the old and new llama.cpp in my app. Eventually everyone will migrate to the new format anyways.

I'm working on a settings page where people can change the parameters. I'm also busy with other things outside of this project so that might be a while (1-2 week)
