 ### Added
 * Adding NetworkSimulator tool (#843). It can be used through the NetworkSimulator component's editor (see the [NetworkSimulator documentation](https://docs-multiplayer.unity3d.com/tools/current/tools-network-simulator/)), but only in-editor. To be able to use it in a build, a custom in-game UI window was added. The in-game UI window opens up automatically when starting or joining a networked session, and can be opened and closed again by pressing 'tab' on a keyboard, or using five fingers at once on mobile.
