Good practices

Hereafter some good practices when you are modding :
 * 1) give a name to your components ; if you don't name your components, the player won't be able to interract with it.
 * 2) respect file architecture ; you must put all your images and animations into the following folders : assets/images and assets/animations into the package app.
 * 3) respect files names ; if not, you world won't be accessible to the players.
 * 4) don't be greedy ; please, do not exceed 4000x2000 pixels for your world.
 * 5) don't be greedy 2 ; the number of your components must be lower than 50.
 * 6) don't be greedy 3 ; the images cannot exceed 1024x1024 pixels.
