Bug when trying to enable the add-on

[LienRag]

When trying to enable the plugin in the Project Settings/extensions panel I got "Impossible de charger le script de l’extension depuis le chemin : « res://addons/cardengine/card_engine.gd ». Cela peut être dû à une erreur de programmation dans ce script.
L'extension « res://addons/cardengine/plugin.cfg » a été désactivée pour prévenir de nouvelles erreures." when trying to enable it in the Project Settings/extensions panel.

This in Godot 3.3.2, Godot 3.4.0 and Godot 3.5.0.

I did put the unzipped add-on directory inside the folder of my project, and I also tried to put the full unzipped directory in the addon directory.
Both were recognized by the "extensions" panel, but both gave the same error when trying to activate them.

Sorry, you cannot just drop the CardEngine plugin in the project like that, this repo is supposed to be used as a template.
If you think you have all the files in place in your project directory, you might be missing the necessary AutoLoads that need to be present before activating the plugin.

You also need the project.cardengine file at the root of the project which contains folder paths that should exists.

PS: I did test this repo against Godot 3.5.0 and its working fine.
