Adds options for grid margins to XYZ Plot and Prompt Matrix

fix symlinks in extra networks ui

Add prompt_hash option for file/dir name pattern

Catch broken model symlinks early | Quickfix modelloader.py

'absolute' and 'resolve' are equivalent, but 'resolve' resolves symlinks (which is an obscure specialty behavior usually not wanted) whereas 'absolute' treats symlinks as folders (which is the expected behavior). This commit allows you to symlink folders within your models/embeddings/etc. dirs and have preview images load as expected without issue.

os.path.getmtime(filename) throws exception later in codepath when meeting broken symlink. For now catch it here early but more checks could be added for robustness.

fix issue with switching back to checkpoint that had its checksum calculated during runtime mentioned in #7506

Add .jpg to allowed thumb formats

Update error message WRT missing checkpoint file

Fix img2imgalt after samplers separation

Move Mac related code to separate file

img2img instruct-pix2pix support

If image_cfg_scale is =1 then the original image is not used for the output. We can then use the original CFGDenoiser to get the same result to support AND functionality.

Maybe in the future AND can be supported with "Image CFG Scale"

Uses separate denoiser for edit (instruct-pix2pix) models

No impact to txt2img or regular img2img

"Image CFG Scale" will only apply to instruct-pix2pix models and metadata will only be added if using such model

Allows instruct-pix2pix

This reverts commit 26983306.

The Safetensors format is also supported.

Move most Mac related code to a separate file, don't even load it unless web UI is run under macOS.

X/Y/Z plot now saves sub grids if opts.grid_save and honors draw_legend

Fixes switch height/width btn unbound error

[Prompt Matrix] Support for negative prompt + delimiter selector

Fix missing tooltip for 'Clear prompt' button

Changes use_original_name_batch to default to True

Refactor MPS PyTorch fixes, add fix still required for PyTorch nightly builds back
