-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.
