Shifted the panda skeleton head for issue #3954. Had to open and save quest_atom1.png becuase I was getting an error running 'grunt sprite'. Committing the generated spritesmithX.png files in dist as well.
Merge branch 'issue-3954' of https://github.com/ebiagogo/habitrpg-shared into ebiagogo-issue-3954
