PSA: If a111 webui becomes unresponsive, try --no-gradio-queue

Ever since they upgraded to gradio 3.2.x I've been having issues with the webui hanging, in some releases it works better in some less.

Basically, if you experience things like the webui stopping updating progress while the terminal window still reports progress or the generate/interrupt buttons just not responding, try adding the launch option --no-gradio-queue

It disables using websockets for some of the back/front communication which to my knowledge is buggy in later gradio versions and in my case solved all these issues.
