* Fix FileSystem::ExecutablePath description
* Add FileSystem::ExecutableFolderPath expression to get the path to the folder where the game executable is located.
* Add expressions FileSystem::DirectoryName, FileSystem::FileName and FileSystem::ExtensionName to extract part of a path.
* Fix FileSystem::UserHomePath expression not working
* Allow to set the position of the window, minimize/maxizime it, resize it,
* Allow to enter a fullscreen and "Kiosk mode" (where the user can't disable the fullscreen),
* Allow to set the window opacity, enable/disable shadow (according to the OS) and use other advanced features.
* Fix "Send variable to all peers" action
* Multiple disconnection from remote instances can now be tracked using events
* Add a condition to detect when another instance connects remotely to the current instance
* This allows to transmit messages on the network to different remote players, enabling simple multiplayer games.
* Read the [documentation on the wiki](http://wiki.compilgames.net/doku.php/gdevelop5/all-features/p2p) to understand how it works, limitations and capabilities of the extension. In particular, for released games, it's recommended that you host a *broker server* allowing game instances to be discovered and connected.
* This adds a **Light** object that can be added on the scene, with a customizable color and radius.
* Add the **Light Obstacle** behavior to the object that must acts as obstacle (walls, etc...) to the lights.
* You can customize the ambient color of the rest of the scene from almost white (useful to show light shadows) to entirely black (useful for horror/exploration games) or any color.
* Use effects on the "Lighting" layer like "Kawase Blur" to achieve soft shadows.
* This brings various upgrades and performance improvement to the internal rendering engine used by games, both in the editor and in exported games.
* This also paves the way for adding new objects like Bitmap Text, Mesh or dynamic lights in the future.
* Huge thanks to @Quarkstar for working on this task and making most of the necessary upgrades .
* Thanks @Bouh for helping fixing/upgrading the Shape Painter object and @Silver-Streak as well as testers from the forum
Don't show the rest in changelog:
* Add a test game with all effects that can be used, to quickly verify they are working.
