Make the launching easier

[Intrivus]

I have some suggestions

Add the Godot icon for the Godot menu and its Launch button
Make the launch button save the current scene before launch?

Replace the debug button(the one that have C# text thingy) with launch button with the Godot Engine icon:

The scene need to auto save when you click it, it is very necessary and when you click the launch button that the PR created earlier you can see that it doesn't build the code before running the game
