Christmas Update

Here's the changes for this update:

• Implemented key binding configuration - Removed annoying scale effect from sliders

• Added Christmas content: * Santa hat * Reindeer horns * Gingerbread nipples * Gift box nipples * Rudolph nose

• Added 3 more scenes: * Forest small waterfall during daytime * Forest small waterfall during noon time * Forest small waterfall during night time

This background scene was suggested by a player, and I liked the idea so I included it for this update. If you have more suggestions about content you'd like to see, let me know.

I hope you guys have a happy Christmas and a happy new year. Cheers
