infotext updates: add option to disregard certain infotext fields, add option to not include VAE in infotext, add explanation to infotext settings page, move some options to infotext settings page

This reverts commit f3d1631a.

This work has been offloaded now into an extension called Prompt Control.

Fix generation params regex

-custom_statics works to do mass replace strings, intended for copy-pasting gen info from internet generations and replacing unsavory prompts with safer prompts for my own sanity
-tried to implement this into generation_parameters_copypaste but it didn't work out this iteration, presumably because we return a string and the calling method is looking for an object type
-updated webui-user.bat to set a custom temp directory (for disk space concerns) and to apply xformers (for generation speed)

I probably won't be merging any of this work into the main repo since I don't want to mess with anyone else's prompts, this is just intended to keep my workspace safe from anything I don't want to see. Eventually this should be done in an extension which I could then publish, but I need to learn a lot more about the extension and callback systems in the main repo first. just uploading this to my fork for now so i don't lose the current progress.

fix for Reload UI function: if you reload UI on one tab, other opened tabs will no longer stop working

face restoration and tiling moved to settings - use "Options in main UI" setting if you want them back

split shared.py into multiple files; should resolve all circular reference import errors related to shared.py

- correctly read values from pasted infotext
- setting for column count
- infotext paste: do not add a field to override settings if some other component is already handling it

add proper support for recalculating conds in k-diffusion samplers
remove support for compvis samplers

print error and continue

rework hires prompts/sampler code to among other things support different extra networks in first/second pass

add some locals from processing function into the Processing class as fields
