components/menu.cs

A UI component that toggles a 'menu' component on a GameObject named "UI" when the Escape key is pressed. It finds the UI GameObject on start, listens for Escape in updates on the authoritative instance, and adds or destroys the menu component; it also ensures the menu is destroyed when this component is destroyed.
