added more robust detection of last line with parameters for pasted prompts

removing duplicated requirements (transformers, diffusers) and reorganizing alphabetically to be able to spot duplicates in the future.

Prevent writing to arbitrary directories, as usual

 Fix to XY_Grid script console progress bar and other progress bar improvements #890 

Clear no longer needed VRAM during a 'highres fix' generation created during the first sampling before doing the second (img2img) sampling. Makes it possible to use the feature on an 8GB card.

Since the other tabs are kept in the dom now filtering is needed.

fixed some [send to..] buttons to work properly with all tabs

rework progressbar/preview to work with new gradio
remove unnecessary create style button
added link to alternative colab

Add option to save before color correction. This helps with some posterisation issues in img2img loopback.
