tidied up + addressed issue with non-LevelTiles

problèmes :
- mon code et l'arrangement des fichiers avait besoin d'un peu de tidy up
- les tiles qui n'étaient pas des LevelTile ne loadaient pas

solution :
- rangé un peu + respecté structure une classe - un fichier
- tenté un build pour voir si tout roulait comme il faut, ce qui m'a porté à ajouter des directives de preprocessing et à bouger les custom inspectors dans le dossier Editor.
- ajouté une représentation simple des tuiles non-LevelTile dans la sauvegarde.
