There are various negative effects if these settings are allowed in the extra options for txt2img or img2img. This PR removes them from the extra_options lists at load time.
'sd_model_checkpoint' and 'CLIP_stop_at_last_layers' will invisibly override main UI settings, leading to confusing behaviour
'sd_vae' doesn't seem harmful, but can create an empty block in the UI section
'forge_additional_modules' causes an error that prevents the UI from loading
empty selection for *Hires VAE / TE* means 'use modules built-in to the model file', same as top-row VAE / TE selection. But this must be written to infotext as something, to distinguish from the non-HiRes case.
adds selection of none/same/different modules for hiresfix
('Use same choices' default option has priority over other selections made at same time.)
includes saving/loading from infotext
* prevent (Managed by Forge) settings reverting to default
* save CLIP skip to config when changed, inconsistent / unpredictable saving behaviour otherwise
- `/sdapi/v1/options` GET now calls `get_config()` from **sysinfo** module, instead of from its own version of the function.
- Defined a new, flexible and more robust `set_config()` function in **sysinfo** module, which:
- obsoletes redundant code
- skips updating values that are unchanged
- has flexible args for both API and UI use
- `/sdapi/v1/options` POST and `override_settings` now use the new `set_config()` function. `set_config()` could possibly obsolete additional functions, but I'm not going to get into that just yet.
- Options for `forge_additional_modules` can now be provided either as the file path, or just the module name.
- Most importantly, `refresh_model_loading_parameters()` is now only called ONCE per request, and **only** if necessary.
- It is now much easier to call `shared.opts.save()` as needed
* Do refresh load params for modules
* Adjust call order for model mgmt/prompt cache
* new function `manage_model_and_prompt_cache()` to improve code clarity
* make unload_model_weights do that
* rename Settings > Actions > unload checkpoint button to 'Unload all models'
* remove (comment out) reload button, as it does nothing and is unlikely to ever do anything since models are loaded on demand
