0.5.13: bugfix, ngrok, ui-ux

✨ stable diffusion:
- changed folder structure: files are now distributed into cuda, darwin, vulkan folders, models in the models folder

- rebuilt for mac and amd cards; increased graph sizes

for low-end machines, i quantized a more heavily compressed q5 model; it should be a bit snappier
