updates

- inpainting

- change second model AD settings to default, first to freenoise. Upscale pass does not work well with freenoise for some reason.

- removed unneeded nodes

- inpainting custom background

- added a third control to the upscale to allow masked background allowing you to set tile at 1.0 strength for it without scaled weights for stablity while still using scaled weights for the subject. Used for after inpainting to keep background stable.

- removed a ton of nodes that were no longer needed.
