SL v0.13 (Android Bugfix) (Patreon)

So, I've been investigating the Android issues and I think I've come up with a fix for the green screen and image errors some folks are having. I've converted all images to WebP and this seems to work wonders (at least in my tests). A big thanks to the66 for the suggestion.

Here is the link to the updated Android build for v0.13.
