Request: Implement as much as possible from the Mikubill repo

[kft334]

Great project and it is revolutionary for SD. I've modified and added the project to my own application wrapped in a flask server. It works pretty well but I would like to be able to use models without merging them like the A1111 extension and also the control weight is a much needed option as well. Being able to set the denoising value would be good too.
