Extra Villagers

This is a smaller update without any new additions. I was working on a bigger update, but found some important bugs that I had to fix, so I released the changes I'd already finished along with the fixes.

• Adjusted the masked villager skins so that their mouths in Fresh Animations match the mask.
• Improved the ocean villager skin.
• Adjusted the mushroom villager's skirt.
• Improved the soul sand valley villager's cloak. None of the above changes are in the pack images yet, but they are visible in-game.
• Added "Fresh-Animations-compatible!" splash.
• Made the drowned zombie villagers emissive, and made a slight adjustment to the back of their heads.
