make CLIP interrogator download original text files if the directory does not exist

- Running arbitrary python code from UI (must run with --allow-code to enable)

- Mouseover hints for most UI elements

- Possible to change defaults/mix/max/step values for UI elements via text config

- Random artist button

- Tiling support, a checkbox to create images that can be tiled like textures

- Progress bar and live image generation preview

- Negative prompt, an extra text field that allows you to list what you don't want to see in generated image
