new gallery code for renpy

Revamping my old gallery code and I'm almost finished, the only thing remained is finding a more elegant way to store the lock/unlock state for images.
it will be available on my GitHub as soon as I finish the last piece: https://github.com/Kiaazad
but if you're in a hurry, it's also available on my patreon as early access: https://www.patreon.com/posts/my-new-image-for-30280712

The finished and free version: https://www.patreon.com/posts/gallery-code-is-30563927
