Add indium-update-script-source-hook

[TatriX]

Usage:

(add-hook 'indium-update-script-source-hook
	  (lambda (url)
	    (indium-eval (format "window.dispatchEvent(new CustomEvent('patch', {detail: {url: '%s'}}))"
				 url))))

and

window.addEventListener("patch", (event) => {
    console.log("Patched @ " + new Date().toTimeString().substring(0, 8), event.detail);
    // rerender, etc
});
