* This was previously causing issues of GDevelop being stuck trying to log in, opening a new window should now open a completely different GDevelop that can be autonomous. (useful to open multiple projects at the same time for instance)
* One or more preview windows can be launched and used with the GDevelop Debugger, like on the desktop app.
* To run the Debugger, click on the button next to the Play button in the toolbar and choose "Start Preview with Debugger and Performance Profiler"
* This is useful to inspect instances of objects, inspect internal messages or run the performance profiler.
* A right click on the Play button will also allow to launch a new preview, in a new window.
* Also fix the loading screen not shown in the preview on the web-app even when asked to be shown (using the game properties preview button)
* Also allow the debugger to work with games run using Network Preview (Preview over Wifi), including on other devices (phones, tablets...)
Don't show the rest in the changelog:
This removes the "live reloading" of the network preview and makes the hot-reloading and debugging to work with the network preview.
