updated interface to use Blocks

added mode toggle for img2img
added inpainting to readme

 image will be upscaled to twice the original width and height, while width and height sliders
 will specify the size of individual tiles. At the moment this method does not support batch size.
 
+Rcommended parameters for upscaling:
+ - Sampling method: Euler a
+ - Denoising strength: 0.2, can go up to 0.4 if you feel adventureous

 This is an independent implementation that does not require any modification to original Stable Diffusion code, and

+### Inpainting
+In img2img tab, draw a mask over a part of image, and that part will be in-painted.
