SD.Next support

[BinaryQuantumSoul]

Hello, a while ago you said you were waiting for SD.Next (vlad fork) to be well-established before making a Google colab for it.
Now SD.Next has improved much, and recent diffusers implementation as well as many fixes make it a really good UI that people without GPU should be able to appreciate too.

So if you're willing to spend time on it, we would be really pleased :)
Have a good day
