 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.

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
