Handling of comfyui based previews 'send to txt2img'

[silveroxides]

Currently if the preview image data is from comfy in json format, pressing send to txt2img does nothing. Instead you need to press every single row below to add what can be added. Only that every time thawt is done it closes the LoRA tab, goes to txt2img and only applies that element. This means I have to repeat this step several time for every row and even then things such as the different spelling and syntax of samplers can't work. So a separate button for sending all the manually added preview parameters would be nice and a search and replace function for the samplers. Below is an example with the sampler name being different. Simple regex operation could handle this. checking for underscores in sampler name and if it finds it, it replaces dpmpp to DPM++, underscores to spaces, lower case to upper case and discard trailing spaces and gpu if present in name.
