Seamless integration of the patreon codes (Patreon)

I decided to improve the game by changing the way the Patreon code (or codes) works.
instead of asking in the middle of the game for a code or displaying a "Patreon required", activating the code before launching the game will automatically unlock the Patreon advantages.
Obviously the activation of the code will be valid on all saves (new and old), and can be activated at any time, because the game will remember the activation of the code allowing you not to have to re-enter it each time that you will start again.
This will allow for a smoother game, without showing those not using the code(s) that they are missing certain things.
