CFG negative prompts

[raefu]

This is distinct from negative prompt weighting, and is used directly by the classifier free guidance process.

Effectively, if you convert the line in webui.py from uc = (model if not opt.optimized else modelCS).get_learned_conditioning(len(prompts) * [""]) to something like uc = (model if not opt.optimized else modelCS).get_learned_conditioning(len(prompts) * ["blurry, bad anatomy, disfigured"]), it will guide the generated image away from images like the undesired negative prompt.

In the UI, this could be either part of the prompt, by extending the prompt weighting to treat negative weights as options for the negative prompt (human:1 bad anatomy:-1), perhaps with a toggle, or another textbox.

That's a very cool idea

This seems to be the only thing holding this web ui down, negative prompts generate such better pictures its not even worth all the extra features this repo has over Automatic1111's simply because of the lack of negative prompts. This needs to be added ASAP.
