0.5.31: sd fix for linux and mac

🛠 added cuda support in sd for linux (except 50x cards), fixed img_gen error, appImage size greatly reduced, resources for koboldcpp, stablediff and whisper moved into a separate folder
🛠 fixed "invalid mode txt2img" error for mac

→ mega
→ gdrive

ran into an issue where appImage wouldn’t launch after updating ubuntu, fix is:
sudo apt update
sudo apt install libfuse2
